--- Comment #16 from Rod Schaffter rodschaffter@gmail.com 2009-07-22 13:22:00 --- The issue still exists in Wine 1.1.22-1.1.26. The modified hack continues to work.
Somewhere along the line ctrl-alt-esc started working for the unpatched Wine when it hung. It usually takes at least three presses to get a functioning Jolly Roger cursor, and then it can be killed. Unfortunately there's no option to save one's work... ;)
