Ink???? System Preferences - Hardware section

Ordinarily, the Ink control panel will only show up if you have a tablet attached--there's not much point in it otherwise. Perhaps you did something that temporarily convinced the System Preferences app that there was one connected, so Ink showed up? It would disappear after a reboot, since you don't actually have one plugged in.

 

Old post, I know!

This has happened 2 times in the last 3 days to me. A small icon appears in the menu bar next to the volume. Also like the poster above has stated, a new option is found in system preferences. It's only their for a few minutes then disappears.
I have a 2008 mac pro running 10.5.6.
I did just get a new airport extreme last week. So I'm assuming this has something to do with the ink icon appearing.

Could it be picking up some stray signal from a neighbor. Who has a wireless wacom tablet?

I would think all wireless pen-devices would use bluetooth. Making my new airport extreme less suspect.
I also double checked, and my bluetooth is turned off. On my mac pro.
Any ideas as to what might be causing this?
