RE: debugger with pop-up-frames non-nil: keeps creating new frames

    Could you post a detailed recipe, so I can try and reproduce 
    the problem?
    A detailed recipe starts with "emacs -q --no-site-file" and 
    lists every
    key typed along with the expected result.
  
1. runemacs.exe -q --no-site-file
2. M-x set-variable RET pop-up-frames RET t RET
3. M-x set-variable RET display-buffer-reuse-frames RET t RET
4. M-x debug-on-entry RET describe-variable RET
5. M-x describe-variable RET display-buffer-reuse-frames RET
6. (in debugger): d d d d...

With each `d' in the debugger, a new frame is created.

HTH,
