    switch-frame                                    << go to frame on styx
    c                                               << WON'T SHOW UP...
    switch-frame                                    << go back to original 
    b                                               << both c and b appear.

That is definitely a bug.  I think I can guess what causes it:
mouse-show-mark uses read-event to peek ahead at the next input event.
That probably won't return till there is an event on the same

I suspect the fix for this will be tricky.  Since it is an obscure
case and not disastrous, I would recommend not fixing it until after
Emacs 21 comes out.
