XXXX Resolved 20170831

See   https://support.microsoft.com/en-us/help/4039884/windows-7-update-kb4039884

on this page it says:

“Before you install this update, you must uninstall any previous versions of KB4039884.  Then install KB4034664 or KB4034679 before installing this current update of KB4039884”

Could not find any previous version of KB4039884 on my machine.  Downloaded and ran:

2017-08 Update for Windows Embedded Standard 7 for X64-based Systems (KB4039884).

I believe the execution also installed KB4034670.  See after-install image of Start → Control Panel → System → Windows Update → Installed Updates below.

Second monitor works again !!!!! for all programs, including those that use Java.  Programs like Maple 2015.2 and JMARS (for Earth) version 3.7.4

Thank you everyone so much for your kind help.  Be careful about downloading Remo Optimizer2.0, it says it is free then all-of-a-sudden they want $30.00.  I made the mistake of downloading it and it did not in any way help me solve the monitor-2 distortion problem.

Regards,

Les

Tried the following with no success:

• Start → Control Panel → System → Check for Updates

  Update for Windows (KB3102810) is already installed on this computer

• Maple update Maple 2015.0 to Maple 2015.2

• Restarted Computer Distortion to Maple 2015.2 on monitor 2 not fixed.

• Followed link  https://borncity.com/win/2017/08/12/windows-update-kb4034664-is-causing-trouble-on-2nd-screen/ Dr Manfred provided.  Purchased Remo Optimizer for $29.97 and ran downloaded execution file.  After restart, distortion still not fixed (see image below)

•  Control Panel → All Control Panel Items → Window Update.  See Review of update history below.  Restarted Computer Maple 2015.2 on Monitor 2 not fixed.  Since KB4019112 and KB4034670 supersede the defective patch-file: KB4034664 is it necessary to delete the defective file?  If so where is the file found?

I went over  this with the techs at the computer store.  I showed them how the Classic application worked and how the Maple (.mw) did not.  And we discussed the other issues about how it worked and then did not work.  They mentioned that I should be able to click-and drag from one monitor to the other, but (for many months) I have had to minimize, then click and drag.  They thought that there could be issues with Windows 2007 Pro but, if it were the cause of distortion when Maple 2015 is dragged from monitor 1 to monitor 2 the same problem would be there with other applications like photoshop, pdf files, web browser, and other applications.  Since all these applications work ok they were in agreement that the Maple 2015 (.mw) was the source of the problem (whether it was loaded as 64 or 32 bit).  It may take a couple of years before I upgrade to Windows 10, at that time I will attempt to load my 64-bit Maple-2015 from disk, if it does not work I will contact Maplesoft and ask for credit toward a newer version.  At this time I plan to "cripple along" with present Maple-2015, but if you get any new information before I update please let me know as it is easier to work with a fully function app.  Thanks again for all your help.

@Christopher2222 

Thank you Cristopher, I, so much, appreciate your help.  I tried re-installing Windows 2007 Pro, but it did not help.  Took my computer to a local computer store that I have dealt with for many years.  We hooked my notebook up to one of their monitors.  The techs all agreed it is a problem with the Maple 2015 software.

@Markiyan Hirnyk 

The data is from test wells in southwest Kansas which draw water from the Ogallala Aquifer. My linear data fit showed conclusively that the aquifer is receding, that is depth to water is increasing, even though the amount of water drawn from the wells is decreasing.  The rate of decline is what I question, exponential curves are common in nature and a linear representation may not be accurate.  Thank you for the information it is very helpful.

Les

Here is an example of data.  

No problem  using 

LeastSquares(THA1a, x, curve = a*x+b)
                   
or

But I dont know how to use an exponential form such as

Thank you so much for your excellent help!

@Kitonum 

Thank you so much Kitonum, works perfect.

Les

Thank you everyone for your kind help.

 I agree with Carl and Mac.  The correct place for the initialization file is  C:\Users\userid\maple.ini  Perhaps it would be helpful to change item 3 in the Create Maple Initialization File help page from

 3) The user’s personal profile directory (multiuser only)…

to

3) The user’s personal profile directory (single or multiuser)…

 The AddConstant command used with the ScientificConstants package will add a constant to a worksheet.  Then, the syntax can be copied and pasted into the maple.ini file, being careful to add a semicolon to the end of each AddConstant command (per Boris, Maplesoft Technical Support).  For example:

 AddConstant(Electrostatic_Constant, symbol = 'k1_', value = 8.987551788*10^9, units = Unit('N'*'m'^2/'C'^2));

Unfortunately, for me at least, when a new worksheet is opened and the command GetConstant is used the following is the result:

It seems more convenient to define the constant as shown in AA11.mw (AA11.mw) and then copy/paste it into another worksheet, along with other declarations, as shown in AA16.mw (AA16.mw).

 I tried designing special units too, e.g., Micro Coulomb ( µC), but it seems easier to use the Units(SI) palette and change values to reflect the units on the palette.  For example, 12.3 cm is entered as 0.123 m and 3.12 µC is entered as 3.12e-6 C .

@Axel Vogt 

Thanks, it worked, unfortunately I seem to be able to add only the one constant (k_).  When I try to add another line to maple.ini nothing happens (in the worksheet).  Nothing happens when I change the original constant either.  Never-the-less your suggestion made a big difference.  Mine is located at 

C:\Program Files (x86)\Maple 2015\lib\ maple.ini

kernelopts(mapledir);

"C:\Program Files\Maple 2015"

@Joe Riel 

Read the Create Maple Initialization File document.  Tried the following paths with same result.

 C:\Program Files\Maple 2015\Users\maple.ini      NO

 C:\Program Files (x86)\Maple 2015\Users\maple.ini    NO

 Error, k_ is not a command in the ScientificConstants package

 There is no bin.win in my C:\Program Files\Maple 2015 directory, but tried 

C:\Program Files\Maple 2015\bin.X86_64_WINDOWS\maple.ini  NO

Tried also 

C:\Program Files (x86)\Maple 2015\bin.win\maple.ini  NO 

C:\Users\Leslie\ maple.ini  NO 

All with same result 

Error, k_ is not a command in the ScientificConstants package 

Could not attach maple.ini but here is a JPEG

Joe,

ProgramFiles\Maple 2015\bin.x86_64_WINDOWS\maplesys.ini

Added last line to contents of maplesys.ini

[user-settings]
MultiUserProfile=0
UserDirectory=C:\Program Files\Maple 2015\Users
Network=0
ScientificConstants:-AddConstant(CoulombForceConstant, symbol='k_', derive=1/4/Pi/epsilon[0]):

Opened new worksheet, added two statements, and get following error

> with(ScientificConstants);
> ScientificConstants:-k_;
Error, k_ is not a command in the ScientificConstants package

Is the place where I added 

ScientificConstants:-AddConstant(CoulombForceConstant, symbol='k_', derive=1/4/Pi/epsilon[0]):

correct?  Any suggestions welcomed.

Thanks again,

Les

Thanks so much Carl!

@Carl Love Carl, I see that I skipped the Product check box when I asked the question.  I will do my level best to remember to do this in the future.

Additionally, thank you so much for the information you sent about single quotes!
