Mark,

You shouldn't have to reboot, just shutdown VFP.

It has been quite I have even seen this corruption occur. Is your machine generally stable? Make sure you are on the latest service pack (or upgrade the VFP9 release is imminent).

>On rebooting the pc and restarting foxpro the problem is still recurring. Any suggestions?
