Seems to be a weird bug with the talent advisor and pvp.

[chaos5061]

Every time I either enter a pvp battleground or leave on my Talent screen pops up. This could be related to another bug I saw with it though. When my bear hunter pet dinged it's 4th talent point the advisor wouldn't put the point in it. So I did it manually but for some reason it still thinks I have a talent point left for it. I don't the talent was accepted by the game and for some reason the advisor thinks it didn't and still wants me to put a point in it. When I close the talent window a box comes up below saying the talent point didn't save but it did.
