Left Click in WoW app doesn't work

A weird thing is happening, I left click on the in-game app to import and export, but left button does nothing. The right activated the change of spec. This only happens from my shaman. my other characters have no problem.

I have disabled all the apps, just in case, but no solution there. Can you suggest another option?

Try typing /amr reset

Maybe it got moved off the screen somehow.

Thank you! I was having the same problem and that worked!
