>>I'm having a weird problem implementing ctl32_scontainer. When I try to run the form that I have placed it on interactively during design time, the ctl32.h file does not seem to processing. It works fine if I compile it, and it works fine if I run it in a separate folder. Any suggestions?

It is. It is also #included in a prg called by the class.
