Thanks for all of your suggestions. I tried changing the theme in the property of every form from (T) to (F). Unfortunately, this did not work at all. The application started in Vista, then aborted when the first form was called.

My application looks and works well in Vista if I set the theme of the Vista machine from Aero to Windows XP. I think I need Foxpro code that will allow me to change the theme of the user's computer to Windows XP at the start of the application, then some more code to change the user's computer back to Aero when my application closes. Any suggestions?

Thanks,
Walter
