The only other problem I can see as an issue is maybe screen resolution/ratio is off and you are not clicking where it looks like you are. Ratios that I have been told by sir work are 2:1, 16:4, and 9:3 or something along these manners. This is just iirc.
what about changing mouse buttons to 0
or using keyboard controls

Whenever that happens to me, double tapping escape to quickly open and close the menu solves it.
