>I have tried changing all of these settings, and I still can't get the title bar to appear (I can't figure out what I did to accidentally disable it). What else should I check? I can't find anything in my base class that would change this property either.

Is this in the form or class that you can't show the title bar? Try giveing it a caption? What is the rest of the code for the class? Can you see the title bar in Design time and just not Run time?
