In the empty frame, no. I sometimes also have an existing client frame that continues to work normally. Typing M-x into this frame works normally. > Does it also redisplay some of the frame?

This is true if I type "M-x redraw-display RET" with the drawn frame focused or the non-drawn frame focused. Would it help to set a breakpoint before typing this command? If so where would you expect something interesting? Cheers, Jon
