>We have an application in VFP with SQL Server 2005 as backend that runs well in WinXP, NT, 98, other WinX but became sluggish when running in WinVista. The forms activates 50% slower than in WinXP or other Winx. Other applications installed in my notebook are even faster in Vista except this VFP App. Is this a known concern already or I am just the one who is experiencing it? I can't test it in other PC yet because I am just supposed to test WinVista so that I could just have a feel on it.

This is good to know. I have been reading other threads and some, however, seems to mention that everything is running ok. There might be something specific to the version you have. What is the exact version of Vista you are using? Other than that, there is probably a factor that is affecting that. Finding it might be difficult however.
