Rpoblem when using chat in game

This has been going on for a few days now and its not game ruining just really annoying. When i try to type in chat it will stop highlighting the area where type appears and my game controls will function normally again. If I press "R" i begin to autorun, really annoying, etc. Anyone know what is causing this problem or if it is even fixable?

From reading other posts, it only happens when the Friends window is open. Anyone confirm this?

It's happened to me a few times, but I haven't narrowed it down to that myself.

After you said that I tried to test it and I think that it does only happen while the friends list is open. It also may happen when the guild menu is open as well, happened to me once but I haven't been able to get it do it again since than.



EDIT: Through some further observation, it appears that the problems happen when people on you friends list log on or off.
