Strange scrolling issue in Windows XP with Midisoft App

[J Guy]

When playing a song in Midisoft's Desktop Sheet Music app in Windows XP the screen freezes and the measure counter freezes after about 50 measures but the audio continues.  Midisoft's suggestion of no help.  The app states it is XP compatible.  BTW, this is a Win98/WinXP dual boot PC and it runs fine in Win98.  Also there seems to be nothing to changes in this app's preferences.  This is the only app with an issue on this PC.  Hope someone has a good suggestion.  Thanks
BTW, this is a great forum.  You guys helped me solve a recent issue when I added additional memory to this same PC.  Seems I needed to change the MaxPage line in the Win98 system.ini.  Thanks

Do you use any peripherals with midisoft's sheet music app?

(Microphone or some other type of external audio input, etc).

If you do use peripherals it could be an incorrectly installed driver or non-winxp driver.

Thanks for the reply.  The only peripheral is the same Midi keyboard I use when I am running in Win98.  What is so strange to me is the software co. sez this app is compatible with Win 9x, ME, XP.  I've never been able to find anyone else running this app in WinXP.  There must be someone that runs it successfully.

It looks like a fairly older application...although they may say it "runs" in XP it may just not be optimised to do so...
Have you tried any other applications for this task ? ?

Have you verified in device manager that there are no "?'s"

Also, have you installed the windows xp driver for the midi keyboard?

Thanks for your suggestions.  So far nothing has changed this issue.  This Midi KBD has no drivers, that is to say the only connections to the PC is the I/O DIN plugs, and the analog audio i/o.
I did notice that if I open say a Lotus 1-2-3 window, then go back to the Desktop Sheet Music app window, the display will again work correctly for a while.
Could there be some kind of conflict with memory allocated to the display?
Also, I have been trying to communicate with the company, IDD, but their website doesn't seem to be working.

The freezing portion sounds more like a memory issue than anything else.

However, have you tried uninstalling/reinstalling the application? 

[J Guy]

I have not tried reinstalling the application.  Seems rather an obvious option I haven't thought of.  I'll give it a try, thanks.

[socrates]

no problem.

[J Guy]

Well, I uninstalled this application and reinstalled it.  No change, same issue.  And now another problem.  See my latest post.

I still think this is the root of the problem.

I agree with patio.  This really should be looked into further.

Have you contacted the company that makes the application to make sure it is optimised for xp?
