I've subclassed the RTF box 6.0 SP2 (IIRC) as olecontrol. Worked fine, as usual.

Then I needed it in another project, and simply wanted to do ADD CLASS myrtf of mylib to \path\otherlib. I got an error sayin "class invalid for this container", which is an error you get when you want to, say, add a toolbar to a container, or a formset to a form.

OK, no big deal, the class had no more than ten properties non-default and no code at all, so it was quite easy to recreate. Still, it bugs me that something like this should happen.

Anyone with similar cases, or at least to confirm this?
