[Octave-bug-tracker] [bug #53217] Can't cancel out the popped up window

[Dan Sebald]

Follow-up Comment #4, bug #53217 (project octave):

Sorry, I *can* reproduce this.  I forgot to change from gnuplot graphics
toolkit to Qt graphics toolkit.  The issue is as I described, but note that
the warning/error message arises from pressing the figure window's close
button *multiple* times.  If one presses the close window just once and then
types 'q' to exit pager mode no error appears.  So, the GUI probably keeps
queuing a bunch of "close" commands for which the figure no longer exists. 
I'll take a look at this later this weekend.
