Patch 2.01 problem! Using the delete key!

[Balkan Warrior]

Hi! I downloaded and installed the 2.01 patch without any problem. But, when I started a new battle, I was not able to use the "Backspace" key to delete a move command for a unit. When I hit the key, a note shows up at the top of the screen that says "3D Model Quality: fastest".

Does anyone have a solution to fix this problem.

Note: The Delete key works fine to cancel a target/fire command.

Thanks in advance.
