My interface seems bugged...

It suddenly happened today when I was in a dung. After I selected a team member, my healing spells did not go to the member but only to myself, and it happened with every team member (Also happened when I was in Dala - my healing spell only went to myself no matter whom I selected!!!) . When I selected a n enemy target, I could not cast any harmful spell as it said invalid target. Also, there was no reaction when I right click my profile or anything else...I have never had this problem before. Don't know if it was a game bug or add-on problem. Anyone else has had the same problem before?

Your problem was that the game mistakenly thought you had the Alt key down, but I guess it fixed itself already.

It happened twice today but I did not know how it fixed itself and if it is gonna happen again...

If it happens again, with the game open and focused, tap the Alt key a couple times.

Will try. Thanks for the tips.
