Thanks for the bug report.
     
     Downloaded PSPP as an alternative to SPSS onto Win7.  Successfully 
installed and run several analysis statistics against very basic data, however 
application continually freezes after several runs.  This computer and software 
very stable development environment.  Naturally the Visual Studio 2010 Ultimate 
debugger comes to the rescue (as always!) and relays the following:
     Unhandled exception at 0x04c69222 in psppire.exe: 0xC0000005: Access 
violation writing location 0x098d2440.
     Call stack location 04c69222()
     Not sure if this is really any help as I didn't download the source code 
to check the exception location or code statements.  Possibly the access rights 
or storage location of the above is protected but this machine has absolute 
administration control even at the software and database levels.

     Version is psppire.exe 0.7.9-g428ee3

That version is on an experimental branch.  Nevertheless, it should not crash 
like that.  If you possibly can get a stack trace, I'd be very interested to
see what it tells us.  I have no idea how to debug on Windows.

    The one thing I am really missing is the math of the calculations say in a 
    right-side panel or separate dialogue pane.  Just me, I like to see the 
full 
    calculations as things are being analysed.  Allows me to check the steps 
taken 
    and the data manipulation and how the final result was achieved.


I can imagine why that would be useful.  I have never seen such a feature.  Do 
you have any screenshots etc, illustrating what you have in mind?

Regards,


John
