BleepingComputer.com: Office Button Pulses Or Flashes. Why? Under What All Conditions?

Hello. Happy New Year!

I have a question. But first, I will make a statement: I have Microsoft Office 2007 Ultimate version installed on my computer. The application I most love is OneNote 2007. Boy, is that a handy program! I don't know what Office 2007 packages offer OneNote 2007. I know for a fact that the Standard edition does not. I think, but not sure if the Professional (the step down from Ultimate edition) version does not have OneNote either. If you can swing it $$$, get it with OneNote! it is worth it! It is fairly easy to use and quite intuitive too.

Now my question: Some of the Office 2007 applications that utilize that new ribbon along the top of the program interface will also have the round Office button in the upper left corner. I have noticed at times that the Office button pulsates or flashes (white to yellowish-gold, back and forth) and at other times it does not, just remains white. Why at times does the Office button pulsate or flash? Under what conditions? ...ALL CONDITIONS IT WOULD MAKE IT FLASK OR PULSE PLEASE. What is it trying to tell me? I have looked on the web trying to find an answer to this and I cannot find an answer anywhere. It can get annoying at times, when I am in Word 2007 and it just pulsates or flashes at me while I am writing a long report. ALSO, what are the corrective measures, if they aren't obvious to stop this pulsating or flashing. Thank you!
