I see no problem in what you're trying to achieve but make sure you changed the CLSID of the project AND the output filename of the OCX to avoid compatibility issue. if someone make a commercial product out of krool ocx and on the same computer the client is using your product, one of the program (eitheir the commercial product or yours) won't load...

EDIT: in the first few post, KROOL made the exact same warning about this.
