Mac Dock not doing the "zoom thing"

Every once in a while I've noticed on our iMac that the dock highlighting stops working. The first icon you mouse over zooms up but it doesn't change if you move over other icons.

I've been Googling for an answer, and it took the right combination of keywords ("imac dock not highlighting") to find this thread on MacRumors.com.

In the first post, a person reports exactly what I'm experiencing. People replied with the usual suggestions: Reboot, Repair Permissions, Reinstall Updates, etc.

On the last post I found this comment:

Hi, I had the same problem but in Leopard. All mouse over effects spontaneously disappeared and stayed off even through reboots.

Once I unplugged and re-plugged my mouse, everything worked fine again.

I suppose if you're on a laptop then plugging in an external mouse might help.

Hope this helps!

I gave it a shot and it worked! I hadn't noticed, but now that I think of it, mouse-over highlighting in general seems to be not right. Hopefully by blogging this, other people will find this solution easier.

How Lame

From tuaw.com:

The Washington Post is reporting that Pandora, the Internet radio station available on Mac, iPhone, and iPod touch, may be shutting down service soon.

The reason is that Sound Exchange, the money-grubbing blackmailers royalties collection arm affiliated with the Recording Industry Association of America, has imposed restrictive administrative fees ($500 per year per channel) and ridiculous royalty fees (2.91 cents per hour per listener) on Internet radio stations. While many companies that provide Internet radio services have been lobbying Congress for relief, there doesn't seem to be much of hope that happening in the near future.
