You didn't answer both of Viv's questions.

This has all the earmarks of a virus scanner interfering with each read/write. Turn that sucker off, at least for VFP files.

The other possiblity is that you are using test data and the user is using production (i.e. larger) data. You might have found something in your code that could be done better.

>>>Does VFP run faster in the development environment than in the runtime environment? I didn't think so but I have 2 basically identical PC's one used for development and the other (my user's) ion which the compiled runtime is installed. My routines run in about 5 minutes on my PC and take over an hour on my user's. My gut tells me the problem lies with the user's PC and not with VFP but the maintenance crew can't seem to find anything wrong with the second PC.
