Something wrong with control setting

I was in the party while healing i press num pad on keyboard (1-8), and suddenly the Option (F11) pop up without reason. I check the control setting, everything has not change. So i did restore default but it doesn't help. I still got pop up option window whenever i press using skill action. It disappear when I repeat same button pushing. When I press F10 both Help Window and Option window pop up same time. When I press F11 nothing happen. Anybody know how to fix it?

Hmm, you sure you didn't spill anything in your keyboard? Perhaps keys could be stuck or the keyboard might just be broken, considering a restore-default didn't help.

Not even to say that spilling something could have caused it to break, could have been other things. I propose that you get another keyboard from around the house or a friend to test out really quick, if the other keyboard doesn't do it then it was just your keyboard's problem, if not, then we'll have to dig a bit deeper.

I had the same problem before. My problem was that my keyboard mapping were all messed up. If another keyboard don't work for you, try remapping the keyboard. Most likely, they are messed up.

Does Num Lock have any affect?
