Gary,

Did you know that Windows7 has an XP compatibility mode.(http://windows.microsoft.com/en-US/windows-vista/Make-older-programs-run-in-this-version-of-Windows) I did this with Acoustica, an old program that was made for XP, and it works great on my 7 machine.
Did you try that?

BTW...I remember when XP came out, their was lots of frustration with compatibility when upgrading from '98. Time moves on, and your software that you paid for needs to catch up.

However if you're happy with XP... so be it. To Each His Own
