I agree with the tables statement, but why did you have problems with classes? I haven't... It's important to work only with the VFP integration, because if you check forms, classes, etc. out in a multi-user situation, re-integrating them could cause problems. However, I usually find working with the VFP integration to be quite smooth, especially in VFP6, where the Source Control window has been replaced with comments in the Command Window.
