Keyboard and Mouse not working in-game in parallels 6 on mac

Hi,

I have an Imac 3.06 GHz Intel Core 2 Duo. I'm running Parallels 6 on my mac with windows 7 Home Premium and Parallels Tools are installed. My mouse works fine on the Parallels desktop. I've just installed Elder Scrolls: Oblivion, but when i enter the game, my mouse bugs. If i move my mouse to fast, it kind of goes back in a laggy-looking way. I've noticed that there's no devices listed in the device list, when i go to Virtual Machine - Configure - Hardware - USB Controller. Also when i pull out a checkbox on the desktop (if you know what i mean - don't know what it's called), it can't follow the mouse properly, like the screen is to slow to show. If i go to the bottom of the Windows window, and checking the Logitech USB-PS/2 Optical Mouse and USB Microsoft Reclusa Keyboard -that i'm using- it works just fine in Oblivion, but the mouse is invisible on the desktop (I know it's there cause i can se the Start menu highlight when i pass it with the mouse) and i can't release the mouse or keyboard from the virtual machine.
I found a guy who had kind of the same problem as me at: http://forum.parallels.com/showthread.php?p=441363#post441363 and he fixed his problem by following this resolution: http://kb.parallels.com/en/8634 but it wont work for me?

Can you help me with this problem? I've tried to fix this for a very long time now. Thanks!
