--- Comment #11 from Peter Quiring pquiring@gmail.com 2011-03-24 12:46:54 CDT --- I wouldn't worry about this bug. The program that crashes is my own and I know how to work around the issue. I doubt many other non-gui apps do window captures. It's just a utility that I made. If the fix might degrade performance I wouldn't implement it.
Thanks.
