wine users - Mar 2011 - Some (Steam) applications not launching

It seems to happen only with Steam games. Sometimes they fail to
'start'. If I go to Gnome System Monitor it says like: 'name of the
process / Sleeping / 63.6 MB / futex_wait_queue_me'.
It happens with a lot of games, sometimes they start and sometimes they got
stuck (the same that was launching before at a later time isn't launching
anymore).

Any suggestions?

Check the AppDB if these games have problems, then follow the instructions if
there are any. If they don't help, run Steam through a terminal and post the
output here when running the games that won't work.
