Do not have VFP8 at the moment. Is there SET TABLEVALIDATE command?
If exists, set it to 0.

Anyway when setting it to different levels you could see what might be wrong with the table.

>I can open, browse and do stuff with a certain table in VFP 5.0. When I try to open it in 8.0, it says the table has become corrupt.

>When I pack and reindex the table under 5.0 the problem is solved but returns after a while, probalby after new rows were added.
