Hi Evan,

It happens only if _MemberData is changed. If you alter the global store all is fine. Only solution I found is closing VFP after reopen all is fine.

As soon as I dragged in a particular class, and it froze VFP, I went back to the new classlib, deleted that class, and MANUALLY created it with no PEM's. The SECOND I tried to open the MemberData editor, it froze AGAIN -- and it HAS NO MEMBER DATA !!!!!!!

I've already output the code out of the class to text files, so it's safe. But WHY THE HECK would MemberData lock up VFP on a BRAND NEW CLASS by the same name in another library?????
