I think it's a bug, because other file operations (including writing text files) work as expected from within a Maplet. It's just writing plots that has no effect...

I have not seen the installer hanging, but if there are no problems listed in the Maple_10_InstallLog.log protocol in your Maple directory, leave it as it is, I'd say. Otherwise report them to tech support (or maybe here, if you prefer). The reboot is necessary for registering fonts on Windows. Without it, you would encounter printing problems, AFAIK.

xvalues:=[2,3,5]: yvalues:=[5,8,11]: xyvalues:=zip((x,y)->[x,y],xvalues,yvalues); zvalues:=[3,7,6]; zip((xy,z)->[op(xy),z],xyvalues,zvalues); If you need this all the time, you might wrap it into a procedure (call it zip3 or so).

About the Uninstall tool that came with Maple 9.5: I've never really used it on Linux (it had some problems, at least on Windows, if I recall correctly), but be aware that a simple "rm -fr" will also remove all subdirectories. So if you installed any packages below Maple's directory, they'll be lost. In particular, the Maplesoft toolboxes, e-Books and the new BlockBuilder will use the "toolbox" subdirectory (and create it if it's not there already). On the other hand, if you want to reinstall anyway, "rm -fr" is okay.

I've answered this question in comp.soft-sys.math.maple earlier today, but for the sake of completeness here it is again: This is due to a bug in Apple's QuickTime 7.0.4 update, which breaks InstallAnywhere (the installer that Maple 10 makes use of). The solution is to reinstall QuickTime 7.0.1. Please see here. As far as we know, only Mac OS 10.3.9 is affected.

There is a C-like preprocessor in Maple (see ?Preprocessor), but it is available only in the Command-line interface. Its $define directive may be what you need, although there are probably better ways: Please post the code you entered so far. The DAE solvers that have been introduced in Maple 9.5 handle IVPs only, but maybe some reader here has an alternative idea. Which Maple version are you running, by the way?

This is a known problem in Maple 10 on Mac OS X with German keyboard layout (maybe other regions as well). AFAIK, it will be fixed very soon. For the moment, you might use 1-D input aka Maple input (please see the Help for more information). You might have to press the space bar after the caret key, then enter the exponent. If that does not help, try the alternative syntax x**2 (very old, undocumented nowadays).

I answered a similar question yesterday in the comp.soft-sys.math.maple newsgroup, but since you mention least squares regression here, I will modify my reply a bit: Besides applying a command such as plot(%,x=0..6); to the output you get from the Assistant when you click the Done button, you could invoke the context menu and select Plots / 2-D Plot (or Plot Builder, if you prefer). This is the more natural approach in Document mode, I guess. Recreating the result (and hence the plot) requires using CurveFitting package commands other than Interactive(). It would be nice if the the Curve Fitting Assistant could generate those commands (and the plot command as well) and return them to the document, just like the Interactive ODE Analyzer does, e.g..

Rounding can introduce errors; it depends on the data and on the Digits setting (to name two important factors). What particular input did you feed to your procedure? What do you mean by the "tutorial for using LinearSolve"?

ListTools:-MakeUnique(STATS) will do.

Maple 9.5 introduced a new package called Logic. Its Tautology command should be the one you're looking for. See ?Tautology for more information.

I guess you are talking about x=-2, right? At x=2, everything should be okay, but at x=-2, RationalFunctionPlot displays a vertical asymptote, which it should not, because the discontinuity at x=-2 is removable. Use normal(y) to confirm. RationalFunctionTutor does a better job here.

I just saw this unanswered question. In case you haven't found a solution yourself, please see ?FileTools,Remove (available from Maple 9 onwards). Unfortunately, this command can erase files only, whereas for directories (even empty ones) it returns "Permission denied". I don't know whether this is by design.

Did you really switch to "4 or 16 colors"? I doubt that drivers for current graphics cards support that, but just in case: Maple needs at least 16-bit color mode (i.e. 2^16=65536 colors). Please see here for more info.

What error messages do you get in which step? Please note that the worksheet you downloaded just demonstrates how to use a package (called MmaTranslator) that comes with Maple from version 9.5 on, but does not provide that package itself. So if you are running an older version of Maple, it won't work.
