Ugh my Intuos3 issues keep on coming. Anyone else have this issue? If I put my pen down either on or off the tablet, then put it back in my hand to use it the tablet doesn't always see that I'm trying to use it again. I can wave the thing all around the surface and nothing. The only thing I can do is pull it away and wait a few seconds, then return it to the surface of the tablet and it works again.
