--- Comment #3 from Sven septim.dt@gmail.com 2010-07-14 13:05:48 --- You'd probably be better off doing a regression test between rc2 and rc3 to determine the actual commit that caused this (as described in http://wiki.winehq.org/RegressionTesting ).
Testing rc4 and rc5 is probably a waste of time, since you already know that the regression is between rc2 and rc3.
