Not every main window resize crashes, but about 1 in 3 crashes, making the program unusable if resize is ever needed.  This machine in Al's old office has Geforce GT 320 graphics (very very old).  I looked into installing the nvidia driver on it but there were too many hoops to jump through, ie it is Linux.
