high cpu load in start menu

I hit the start menu button, and set my mouse cursor over the browse files folder, then drives, then control panel. Its stuck trying to open it. The cpu load hit 100% immediately when I set my cursor over this menu. Havent figured out if its the virtual machines fault or reactos's.

I got this message in the command prompt when opening the virtual machine:

Could not open \\.\kqemu' - QEMU acceleration layer not activated

Could this be the problem or is everybody getting similar results?
