I'm having an odd problem with my current Windows 7 Installation. Every time I had an UAC prompt, the image turns over-saturated before reverting into the correct colors again. Running color calibration only helps before rebooting as reboot usually re-enact this problem. Reinstalled GFX drivers with no avail. Any ideas?
Image follows later.
