Problems with X, drivers or something else?

Heyho,

The problem:
While using the Desktop (Xorg) I always have the strange problem that I just can use the Top-bar (Menu, etc), the window itself or the Bottom-bar (switch windows). For example, starting the commandline I can't go into the menu or switch to Iceweasel to look up some commands, neither with Keyboard nor Mouse, until I close the commandline. (It's weird, hope somebody understands what I mean ;) )

Today I've just installed the newest version with another monitor (Motorola Lapdock, normal monitor is Acer G245HQ) and I had no problems using it... Normal Keyboard and Mouse weren't attached, too. Somebody has an idea, how this can occur?

The graphics card is a Gigabyte nVidia GeForce GTX 660, the drivers seem to be preinstalled on Kali.

Thanks
Cork

Problem solved, found out that it's my RAT 5's (the mouse) fault, there is a problem because it has "to many" keys ;)
