>CLEAR CLASSLIB removes a class library from memory that was loaded through SET CLASSLIB TO.

Thanks Jim,

Now that you told me again what I already knew :), I went and test this:
-open a form in form designer (this will load the classlib)
-exit the form designer (class still in use)

-issue CLEAR CLASSLIB myBase - NO EFFECT (class still in use)
BUT
-issue SET CLASSLIB TO myBase
-issue CLEAR CLASSLIB myBase - this WILL clear the class!

So, in order for CLEAR CLASSLIB to work all the time you'll need to precede it with a SET CLASSLIB TO...
No big deal, but it doesn't look quite right to me. At least I know a work around it...
