According to the blizzard forums there is a bug in wine due to the recent BEAST attack (http://us.battle.net/wow/en/forum/topic/20742995286?page=11#201) and apparently the fix requires a patch for wine 1.9.6 (http://us.battle.net/wow/en/forum/topic/20742995286?page=11#203).
Any ideas on how to accomplish this, or is this post enough for a relase builder to make a stab at this?
I am a little new to requesting things here, so forgive me if there is a more appropriate method that I have missed or glossed over.
TIA,
Andrew.
Fixed with 1.9.7.
