So yeh there is an issue with the card selection screen when initiating a game of caravan. It has happened twice to me with the guy from Vinnie and Vance Casino and once with the guy inside the dinosaur (wasn't going to waste my time trying again). It appears to happen most when I try to change the cards in my deck and especially if you use the mouse to control the slider.
The game stops responding, amd drivers restart and game continues being non-responsive until I close it.
Specs-
Win 7 64bit
Core i7 930-2.8ghz
Radeon HD5870
6gb RAM

I am running game on absolute full graphics with no problems except mentioned above.

On a side note- how do I change the cards in my deck for those I have purchased/found?
