>i recently had reason to delete a button from a form and then save the program. i then did an undo to get the button back, however the code in the valid of the form was complete rubbish when vfp put the button back. has anyone got this before?

I was able to duplicate this problem in VFP7 but not in VFP8. Time to upgrade? If you need to you can be careful to not use any of the new features in your applications, but take advantage of the development tools in VFP8 and then recompile in VFP7 for distribution.
