No crash with testcase, but has a question.

Smaug:  Attempting to drag the frame border doesn't crash, but it also does not move at all.  I lose the "drag" mouse cursor after clicking on the border.  Is that expected behavior?  If so, we're good.  It not, I need to revoke my v.fixed.  Let me know.  Thanks!
Sounds like a some sort of repainting issue.
But the crash itself is related to dragging the border and once the dragging starts, the border is actually deleted.
But if there isn't a crash, this particular bug should be fixed, IMO.
