--- Comment #3 from Peter Lawler winehq-bugzilla@six-by-nine.com.au 2007-08-19 22:10:54 --- It helps if those closing the bug appreciate the issue before just assuming stuff. I've been in discussions with the mlankhorts and Thunderbird, and this is definately a bug.
For the record, switching to 'emulation' results in no sound/hang/crash as well.
But, meh, to quote vitamin, whatever.
