The display of mouse coordinates of the win terminal
get's garbled sometimes on my WinXP machine.
This can be reproduced e.g. by moving the plot window
partialy of the screen. When the window is moved
back onto the screen the mouse coordinate display in
the lower left corner is garbled.
Looking at the code I see that there's some XOR
operation involved. Could it be that somehow the XOR
mechanism and the window content get out of sync?
This is a cosmetic issue and in my opinion not
release critical for 4.2.
