>>I'm issuing SET CLASSLIB TO MyClassLib in the 'main' program of an app in VFP6. This main program can be re-executed by the user if they need to log in again. The first time executing, all is fine, but when the SET CLASSLIB TO executes a second time, the CLASSLIB winds up being set to null! I cannot duplicate this behaviour from the command line. Does anyone know why this might happen?

Thanks Mark. I had already put something like that in as a work-around but I was trying to figure out *why* this was happening. BTW, your second line should have read SET CLASSLIB TO MyClassLib ADDITIVE if the assumption was that there were probably other classes in use.
