Both Interactive stock quote importer applications in the application center are for Maple 13 and Maple 15.

Can anyone help to get it to work in Maple 12?  Does the Maple 13 code still work today?

The error I recieve running it in Maple 12 is, Error in Component Button0 with caption "Get finance Data from Yahoo" (in assign) invalid arguments.

I have a sample waveform of an air conditioner and want to see if any low frequencies (10 Hz which is harmful to human health) exist in the wave.  How can I do that?

Granted the frequencies picked up in the recorded file depend on the quality of the recording and the recorder and lower frequencies may not have been picked up. 

I've looked at

I wish to view the complete internal workings of the code (specifically the SHA code created by Joe Riel)

I tried  ...

interface(verboseproc=2)
print(SHA)  #appears to show a limited amount of code

showstat(SHA)  #shows some code but it's not complete

march('list',"c:\\testlib\\SHA.mla")   # not exactly what I thought it would list

How do I view the code? 

Is there a way to select multiple entries in a ListBox component? 

On a similar note but continuing a Roots discussion

Roots(2^(cos(x))-5)

produces the error    Warning, the expression has an infinity of potential roots, but none could be confirmed  However we know there are none (I'm pretty sure) and Maple should return, No roots exist from this expression. 

Although Maple correctly returns an empty list using a range or numeric option.
