>I worked under 98, win2k and now for a long time working on XP pro. I didn't see any slow down. Probably it's something in your installation, hardware, network, virus scanners etc or the code itself.

Thanks for your attention, however I don't think this matter relate to hardware or network, virus scanners, because the trouble machines belong to different clients, and the variation of config. is huge. Furthermore, one of the machine is running on its own - no server and no other workstations, and one of the machine hasn't any virus scanner.
I also don't think it is related to coding, if coding causes slow down under WinXP, then it should cause slow down under 98 and win2k either, unless there is somthing new in XP that makes program behavior different.
You said installation, that may be a possible cause, I can try to install a copy of VFP to the trouble machine and see if it makes improvement.

Anybody out there has the same experience? Am I alone?
