I took this approach. Unfortunately it looks like all box-related frames other than menubar should have had this bit set in the past; however, judging by what happens with my IsFrameOfType implementation, they didn't. I need to figure out which of them, if any, actually had the bit set, and why the code in ConstructXULFrame didn't do what it looks like it did. -David -- L.
