I was in the 5k tourney and while I was playing, the menu poped up right in front of my game with nothing in it (Free play, Torishop, Setup...), just a red square with the TB logo. As it poped up, I couldn't do a thing beside moving the camera on the fight behind it. I couldn't get it off until the end of the fight.

did you tried pressing esc maybe?
or doing alt+tab or maybe clicking were the resume thing would be?
Also was this the only time it happened to you?

i've had this happen to me before too. in a full betting server whenever i hover my mouse over a link, this would happen.

Its happen with me too,I closed it clicking in the red square,or pressing esc,idk

This happened to me too once in a tourney

Dang even Hannw, tunadao and killer had this. I tried to press esc and tried pressing in the red square since it didn't work. I didn't try to press alt+tab, didn't thought about it at the moment.
This is the first time it happened for me.

This happened to me alot of times
I press esc
