First Mobhack and FASTBOAT TOUGH thanks for the replies
Mobhack thanks to you i found the issue
I wanted to see if the taskbar is set to auto hide and saw a little option called "Use Aero Peek for desktop preview", i deactivated it and e voila it runs in normal colours. I thought this would be deactivated autmatically if i deactivate Aero.
So again thank you for your time and help
