Nice, Rhett does the exact same thing (he was doing it a bit earlier but he is out terrorizing the cats at his moment. You'd think that after a year they would be able to live happily under the same roof).
The only solution is to put the computer down unless I'm doing work stuff then I have to move to the kitchen table.
It's great that our dogs can communicate to us when they want some attention. Bailey is a little less suttle when I'm on the computer for a while. He just jumps on my lap while I'm typing and demands some attention.
Booker's trick in this regard is to go to my right side with the mouse, stand up, put her paws on my arm as it is outstretched to the mouse, and then DIG in her claws until I have no choice but to stop working on the computer and give her attention!
