Can't click on lists and open inventory window

Hey,
so apparently for no reason I can't click on lists (like chat sets [FC, tell, etc]) neither open my inventory window. When I try to open these things they instantly close, like it was automatic.

I don't know if theres a command button or anything that I might accidentaly pressed but it start to happen this morning. I already restart the windows and tried to plug off the gamepad that was connected (since I play with keyboard and mouse). Nothing.

Its getting really annoying cause I have to type /fc and /p all the time. Anybody already had this problem?
