Invoke your desktop's Run Command interface (usually ALT+F2 does the
trick) or a terminal and use it to run `xkill`.  This will turn your
mouse arrow into an X, and you can then click on anything on your
screen to kill the process underlying it.  Please note that in the
case of Flash this may take your entire browser process along with it.

Speaking of your browser, which one do you use?  This used to happen a
lot back in the bad old days, but I haven't heard/seen this happen in
_years_.
