--- Comment #11 from Jeff Zaroyko jeffz@jeffz.name 2009-01-03 07:34:08 --- still need you to figure out how to run a regression test, if you get different results for these problems from the regression testing then file seperate bug reports.
try: git checkout master git bisect start git bisect good wine-1.1.11 git bisect bad wine-1.12
and continue on from there... if that doesn't work then visit irc or wine-users to ask for help with git.
