Good Morning Folks!
So, there are reported issues with the Hallows End Boss. Some are a misunderstanding in how the new system works with points, others are an issue related to the cog-wheel issue that's been previously observed in BGs.
Unable to load in, or WoW exiting upon arrival in the instance.
This could be a number of things, many cases may be related to the cog-wheel issue that is already known.
I'd recommend everyone reload their UI, just in case. If it's the cog-wheel issue - avoiding mousing over is one way to avoid it happening. Our developers are still looking into that issue.
To do a full and proper reset UI....
Q u o t e:
To do a full reset UI, you will want to save your addons in another spot if you wish to preserve them.
Then rename/delete or move your WTF, Cache and Interface folders while WoW is shutdown. Reboot your system.
Note, if you are running Vista make sure your permissions are set so it does not undo your changes.
More detailed instructions for different operating systems, including Macs are here.

This sort of explains why Occulus locked up for me the other day since there is a cogwheel click option at the beginning when you get in as well as other lockups in instances when I load in thanks to other cogwheel related devices(mage tables, lock stones, portals, etc). I will be trying this UI reset she refers to in there as well as another suggestion I came across. Some have reported success by unchecking the 'hardware cursor' setting. I'm going to have to experiment and find out what works for me if anything but its at least something until Blizzard fixes it. Their dev's are working on it!
