I tried to fix this in one way last fall, by changing select-window
not to alter the frame-selected-window in some cases.  That caused
other problems.  So in December I undid that change
and tried another fix:

        * window.el (save-selected-window): Save and restore
        selected windows of all frames.

If this doesn't fix te problem, why doesn't it?
