PSA: When I click, sometimes my game changes from full screen to windowed

[myxomatosii]

I feel like with so many new players, this will be common enough problem to be in Server Chat where more will see it.

Its because when you changed from windowed to full screen, the windowed version wasn't covering up the part of the screen where you clicked. Re-size the windowed version to take up as much of your screen as possible before changing to full screen.

Hope this helps anyone with the problem.
