I believe this is actually a Steam client bug which affects Windows users as well. So it's probably invalid (as a Wine -related bug report)...
Valve Steam User Forum links as "proof"... http://forums.steampowered.com/forums/showthread.php?t=3076162&highlight... http://forums.steampowered.com/forums/showthread.php?t=2615916&highlight... http://forums.steampowered.com/forums/showthread.php?t=3075988&highlight...
Probably it is, but just some of win users have that problem. If it affected to ALL users, it would immediately resolved by the Valve.
By the way - under win7 i don't have any problems with it.
