I was playing a game and during the match i needed to check if the wlan was working.
I pressed Ctrl+Alt+Del and launched the task-manger, but when i refocused on BB2 the interface was not accepting the click of the mouse buttons or using the keyboard, while moving the arrow was still working and the camera panned the field accordingly.
I tried also the scroll wheel and it was working, but none of the 3 mouse buttons was usable
