Re: PS to previous message about popping up leaving nothing selected

[Moon@MIT-AI]

This happens with either menus or text windows, when popped up over the
blank window, and doesn't happen when popped up over just the editor window.
The right way to fix it is probably to give the blank window a way to refuse
to be selected so that WINDOWS-AUTOEXPOSE will find someone else to select.
Alternatively the blank window could pick an editor window and select it
when someone sends it a select message, which would be a kludge.
