Can anyone tell me if you can (or are allowed to) create new classes in a Mere Mortals Framework application based on VFP base classes instead of subclassing them from Mere Mortals classes?

I've found a free OutLookBar class that has two objects in it, a toolbar and a container, both subclassed from VFP's base classes. When I add them to the project and run the app from the IDE it runs beautifully. However, when I build an EXE and try to run it, I keep getting this error:

"The following system error has been encountered:

Any ideas?

THANKS!
