Not sure that it will fix anything, but you may try to avoid putting rtfbox (or any other activeX) directly on the form. Subclass it somewhere, then put that subclassed control where you need it. The instantiation is somewhat different - some activeX controls used to detect direct instantiation as "used in development" and would start checking for development license; if you instantiate a subclass, it detects a runtime instantiation, and all is fine. Not sure that this approach would change anything in your case, but it may be worth a try.
