Arma 3 crash to desktop

[TheMiG]

Hi guys.
My arma 3 has crash (not responding) and I am unable to close it or click on anything on the desktop to that matter with the exception of the taskbar. Is there a way to close it without restarting my Pc? I've got some important applications that I'm I'm the middle of in chrome that I can't risk losing.
I've tried alt f4, alt tab, I can't close from the task manager because I can't even click the damn thing.
Thanks.

If you are playing through steam, you could try 'Verify Integrity of Game Cache'.

This will scan your game files, and replace any that appear to be damaged/missing. This will not erase your player profile.

Found a solution. After opening the task manager simply use the arrow keys and or tab to navigate to the desired program and press 'del' or delete to close it
