Capturing screenshots was a problem...

I experienced some problem with Fraps in games like Grim Fandango: it's impossible to capture a screenshot.

So I downloaded this software, ShareX, the successor of Zscreen and put CTRL+PrintScreen to take screenshots.
With the only PrintScreen or Fn(eg: F11) nothing happened playing Grim Fandango, I suppose some "hotkey" problem, but now works like a charm.

ShareX saves and uploads images by default, so set your config.
