vista Not reverting to high resolution after full-screen game

[Lirodon]

Okay, here's a perplexing issue;

Right now I have League of Legends set to run at 1440x900 full-screen mode instead of 1680x1050. When the game ends and it goes back to the desktop for the lobby, it doesn't revert to 1680x1050, but 800x600. But the real kicker is that when I go to the resolution menu to change it back to it, it reverts to 800x600 if I choose 1680x1050 again. Yet, if I log off and log back in, it does let me choose 1680x1050 again.

What is going on here? If it helps anything, I have a Nvidia graphics card with recent drivers.

I had the same problem but with new 680. Had to RMA it.

What exactly do you mean by RMA?

RMA - Return Merchandise Authorisation.

Basically, it's a reference number so the retailer can accept the graphics card back for testing - usually only applicable if it was purchased from an online retailer or directly from the manufacturer, as it would be just as easy to hand the card back to the computer store you purchased it from.
