Due to the design of my laptop, I sometimes right click by mistake. There seems to be no way of getting rid of the little box once it comes up and all my buttons freeze, the game is still running but I can't do anything, not even close the screen. I have to use program manager to shut it down and then sign back in.
It is one of those small but really, really annoying things I hope you can fix sometime :)
ETA: I am using Firefox for Glitch alone, if this makes any difference!
