I've recently upgraded to 10.3.1 (from version 9.1.0) and discoverd the following bug:
When I use the line tool and move outside the window (and outside the edges of
the image) the program hangs or closes instantly after you release the mouse button.
This can be reproduced but doesn't happen every time (mostly if I haven't saved for some time

and made some changes to the image before. I'm using size 20 and it casshes mostly when drawing
long lines). Sometimes an access violation error occurred and I could resume working, but
mostly the program just crashed.
Had no problems with the older version, though...
(I'm using a server as workstation with ECC memory, so there shouldn't be a problem with the Hardware)
Kind regards
Mathias
