Thanks Bo

That gives me something to work with.
I'll look into these.

>You may try unloading any dangling rtf dll references and see if that clears it up. Try running this code after invoking Crystal and closing any VFP form with an RTF control in it. There should be zero references. (IMPORTANT: If you have an RTF form open when you run this code it WILL crash VFP)
