alt tab + game freeze + sound continues

[shummit]

im currently using dual monitor, when i switch from EQ (WindowMode) to facebook or any other application, it will cause the game to freeze up (sometimes), but i can still hear spells and the sounds from the game.

any idea's on how to prevent the freezing? it gets quite annoying when i switch to facebook or netflix.


just a little info on the rig i am using;

Win7 64bit
Quad core - set the launcher to a single core to prevent other issues
Nvidia 250 GTS ( latest driver )
