[OS X Emacs] Re: one-buffer-one-frame-mode strangeness with Spaces

[Rosanne Zeiler]

  Hi all,

This may be related to this problem. I very often have multiple frames 
of aquamacs open in several spaces (some with multiple tabs). One of the 
problems I have is that using cmd ` switches only between two aquamacs 
frames, even though there are more than two open in one space. (cmd 
shift ` seems to switch between just two frames in different spaces). 
The other problem is that when I close an aquamacs frame the space 
switches automatically to another space where there is an open aquamacs 
frame. I haven't had time to check these things with the debug version, 
but this seems to suggest that the spaces thing is not neccesairily 
linked to the one-buffer-one-frame-mode.
