--- Comment #4 from John john123@openmailbox.org --- **UPDATE**
I may have stumbled upon a workaround for this issue.
As of a few minutes ago, this Bug no longer presents itself, i.e. the WoW client will connect when launched via Battle.net.
I did two things that may have worked:
1- I contacted Blizzard and removed the 'starter edition' from my Battle.Net account, and 2- changed the Windows Version to 'Windows 8' in Wine config. From that point on it worked, even when I reverted back to Windows 7 (original setting).
Not sure which, if any, of these steps helped.
I have **just** tested this in both 1.7.26 and then reverted wine back to 1.6.2 the Bug cannot be reproduced.
