Blinking light on mouse?

The manual's troubleshooting page (the last page before it changes lanugages) says this could be a sign of batteries not having enough voltage.  It says (I'm copy/pasting)...

If you have rechargeable batteries in your mouse, try checking the battery status. In Windows XP, click Start and Run. Type in main.cpl and then click OK. In Windows Vista or Windows 7, click Start and type main.cpl into the Search field and press Enter. The Mouse Properties dialog opens. If there is a Wireless tab, go to it and verify the status of the battery. If there is not a Wireless tab, try recharging your batteries or the mouse itself, if it is rechargeable. Use a different outlet or port than you typically use to charge the mouse or the batteries.

If you do not have rechargeable batteries, replace those in your mouse with new, alkaline batteries. In fact, if you do have rechargeable batteries and the problem continues even after recharging, try using fresh alkaline batteries. Your rechargeable batteries may not be holding a charge.

The jumpy scroll wheel can be fixed by switching off the mouse, holding it upside down against your thigh, and quickly rolling it back and forth to make the scroll wheel spin quickly, breaking off the corrosion from the pickups inside the wheel mechanism. I have to do this once a month or so but it works like a charm every time.

I just had this happen. I was going nuts. I finally got it to stop by taking both batteries out at the same time, waited a minute and put fresh batteries back in. It stopped blinking. Before, I was taking out and replacing one at a time. Hope this helps.

but what if you just put fresh ones in like a week ago?
