Annoying Recalibrate Monitor Warning

Starting yesterday, every time I restart my Mac, I get a pop up window telling me that I have passed the maximum recommended time between monitor recalibration and that I should do it again as soon as possible.

Where is this warning coming from, and how can I turn it off? I am using Spyder2 hardware based calibration, and in fact just did this last week. Clearly the above warning must be coming from somewhere else that is not aware of my other calibration.

Any and all help much appreciated.

It is coming from the Spyder software:

Thanks! It was indeed right there, hiding out in the Preferences panel of the Spyder2Pro software. MUCH appreciated!
