I have this listed already as an un-fixed bug.
"pause mouse" should return immediately, perhaps with a warning,
if the there is  no mousable window present.
Here are my notes:

 - If an x11 plot window is killed, then a subsequent 'pause mouse'
   command should be rejected.  The only way I have managed to set this up
   so far is to have event_reset() set term_initialised = FALSE,
   and have pause_command() test for it.  This seems to work for x11, but
   I have no idea what havoc it might trigger on os2 or whatever else.
