--- Comment #83 from Octavian Voicu octavian.voicu@gmail.com 2010-07-16 19:13:59 --- I also noticed this a few days ago. I used to apply the workaround which involved commenting the SetForegroundWindow line, but now it's not necessary anymore.
Either some commit fixed this, or the latest version of Eve client is not affected anymore. Maybe someone can test wine 1.2 with an older client; as I recall the crash on Alt+Tab would occur even before login, so it could be tested with an older client.
