[Wine] Source games not letting me tab out.

[theShaggy]

Hi guys,

Up until recently, I've been able to tab out of Source engine games (L4D2, TF2, and so forth) without a problem.  It's never given me an issue before, so I can tab out and check for IMs and such.

However, recently it won't let me do so.  It may have been because I reinstalled Lucid Lynx Ubuntu, but now if anything brings the taskbar to the front, the game still runs but it won't let me refocus.  The taskbar stays up, and the gamescreen shrinks ever-so-slightly, as if it is in a window-picker.

What could be doing this, any suggestions on how to fix it?  Other games seem to work fine.
