Guild Wars 2

I tought my settings menu had a problem but actually its about double-clicking. My mouse works fine i can double-click while the game is closed but i can’t do anything that requires double clicking in game. Please help me.

I will try repairing my client. Thanks for the help !

EDIT : Repairing didn’t work i am losing hope maybe my last chance is to redownload.

I tried clicking once, double-clicking, triple-clicking everything. I dont know if i am being stupid here but that little box never shoes up.
