Agreed, turns out that it was the one I was using myself too. Until I just swapped it out for calculator plus. The only issue I had was that I wasn't able to setup a keyboard shortcut (Ctrl+Alt+C), but just figured that one out.

Turns out that if you create a shortcut via the send To "Desktop (Create shortcut)" that you can then set it up a keyboard shortcut via properties. As long as your shortcut is on the desktop or in the menu then the keyboard shortcut works. Yay.
