ive mentioned it before that i use my keyboards keypad to quickbind the inventory so i can grab items on the fly, and that for soe reason the top and bottom layers flip randomly mid game. but now number 7 has become the windows live key (something thats just stupid and obstructive as it is, i use the home key a lot in games) so now im constantly pausing the game just trying to get my weapons in mercs without being facefisted. can ANYONE help me with this problem?

edit...fixd the windows live thing, my numpad lock went off, the light doesnt always stay on the right setting...i drop this thing a lot...in fact i have one last spare under my desk lol.
still having inventory flipping problems though.

In the keyboard/mouse settings
There is a
"Item Menu Prioritization" tab, you can pick either D-pad style, or Numerical

I'm not sure if this is what you were talking about, but it;s the only thing that comes to mind.
