Monitor Calibration - Dialog label background can be seen now!?

[owaters]

Hi,

I used the Spyder3 Pro by Datacolor (hardware monitor calibrator) to calibrate my monitor and ever since I can see all the label backgrounds in dialog boxes.

(screenshot attached) - I have boosted the contrast in the lower screen so the problem can be seen better.

This happens in every Apple dialog box, throughout the OS. Some apps dont seem to be affected by it. Preference windows (like the one in the screenshot) display correctly once flicking through the tabs.

I'm not sure why this is, anyone have any idea? How can this be fixed?
