For Science! :
I made sure that Steam Overlay is off, to see if that was the problem.
I booted up the game, did some moving around, using the numpad, worked.
I did 3 ALT-TAB’s and messed with the desktop, still worked.
I invited my friend–Tapped a the same numerical-keyboard key I used before-- BANG!
V-Squashed Low-Resolution Video, as seen in the picture. The screenshot did not work.
NOTE: This repeatable system-locking bug is caused by a Co-Op invite!
Please fix this.
Oddly, I just got my Member privileges.
