So, I'm having a TERRIBLY unique event of occurrence.
I'm running vindictus in VirtualBox Host OS = Windows 7 X64 with amd athlon II x4 640, 6 gigs of ddr3 1366 ram, an ATI HD4870 graphics card, and guest OS = Windows XP 32 bit.
Vindictus plays JUST fine, literally the best performance I've EVER gotten in ANY virtual environment (sexy freaking program you have here.)
However, when I run the game, which requires directx the mouse ONLY moves to the left whether I move my physical mouse left, right, up, or down.
However, when I hold ALT in game, to "release" the mouse into "free mode" and right click, which enables moving the camera it works just fine (just a LOT slower than normal tracking method for the camera.
I have tried enabling, and disabling Mouse integration, and pretty much EVERYTHING else that i can think of including the sensitivity settings in both the Guest OS, and the game.
Can anyone help me out with this?!?
Thanks for your time, and I hope I was thorough enough in my explanation since I know not everyone plays this game.

Disable absolute pointing device in the VM settings too.

It is disabled, tried enabling, and disabling with combination of other mouse options, still doing the same thing.

Did you install anything else concerning a mouse in the Guest?
