Mouse is off-center

[ThePastaGoddess]

So I got on and I tried clicking on the Login button but it wouldn't show the button was highlighted. I moved my mouse over to the left and it was highlighted and I could click it. The same thing happened in both the game and the Login screen, so I tried restarting the game and the mouse kept being off-center. My mouse isn't off-center when not in the game, so I'm not sure if I could fix it. I'm using the latest version, I have Windows and experienced no other signifigant problems.
(Sorry if I posted in the wrong place, or missed some information, I'm tired. )

I'm having the same problem.

I will admit I held this issue when setting up a fix I can suggest it taking the game out of full screen then the centering issue disappears

Yay thank you, that fixed it!

Sorry if this is a stupid question, but how do I get out of full-screen?
