--- Comment #4 from Alexandre Julliard julliard@winehq.org 2012-07-25 07:24:11 CDT --- It's hard to tell without seeing the trace. You can try attaching the debugger when it's hung and do a 'bt all', that may possibly give a hint. Also feel free to email me the trace privately if you are comfortable with that.
