Roger Binns reported this bug: Start Xemacs View -> New Frame Open up a few files Then in the frame that doesn't have focus, click on the buffers menu and select a buffer. Focus gets transferred to the new frame, but the old frame is the one that has the buffer changed. I would expect the buffer to change in the frame whose buffer menu I clicked on. I can confirm this behavior on my native XEmacs (21.4.14+) running on my WinXP box here are work. Apparently, this only happens if you have not previously selected the frame. This problem does not seem to occur under Unix. - Vin
