I'll have to do a search of the MS KB on this, Chris. Hopefully, since we're in 7.0 this will be something that's been fixed.

The only problem (so far) that I've had is that the VFP upsizing wizard (even in SP 4) wants the compatibility level set no higher than 6.5. So it's been into the Query Analyzer, set the compatibility level, upsize the table, then set it back.
