>We have an older Foxpro 2.6 app that everyone in our office uses all day. We have started to convert the app to Visual Foxpro, but that is still a long way off. On some newer machines, we have started to move to Windows XP. The problem we are having is that when the Fox2.6 app is running, windows performance slows to a crawl. Does anyone know of a way to increase performance when running a DOS Foxpro app under Windows XP?

Have you tried running the fox for dos code under vfp?
As I recall, CLOSE DATA and I think one other command was all I have had to do with old apps to get VFP to handle things ok.
