When I click Sims 3 via Origin or from the game icon to start the launcher everything gets huge

I've seen this phenomena a few times too on my desktop monitor, but only when the game stops responding and has to be force quitted via the task manager.

The native resolution of the screen is 1920x1200, but when this occurs it must be less than half of that. Everything is 2-3 times bigger than usual, and it looks so funny it always makes me laugh.

I have no idéa why it happens, or if there's anything you can do to prevent it, I just restart the computer and that brings everything back to normal again. :)
