You probably don't want to read this message unless you landed here with a Google search. This is a message of hope to all of you Wacom users that are experiencing this very bizarre behavior with your Graphire or Intuos tablet on a Mac. (I'm using a Graphire... for now...) That said, I hear it's also a problem with Cintiq tablets. Here are the symptoms:
- When you draw short strokes, the cursor jumps back to the beggining of the line for a fraction of a second.

- At first, this seems like a lag problem, but it's not... it's specific to short strokes and always involves the cursor jumping back.
- Thus, if you draw a series of short strokes (for example, writing words), your lines will stutter and be all over the place (and look horrible).
- It works fine on a PC.
- It doesn't do the same thing with the (Wacom) mouse.
- Problems are worst in Photoshop or Painter, but they actually do exist elsewhere in the system (it's just not really noticeable much).
The problem is that you have your "Double-click distance" too far. ...I found the solution, after much searching, on an
Adobe forum. The solution is to go to your System Preferences, Pen Tablet, Pen, Double Click Distance, and pull the slider all the way to the left (older versions of the driver may even let you turn this off). ...Of course, it doesn't need to be
all the way to the left... you can experiment with what works, but... you get the idea.
Basically, the driver is causing the cusor to jump back to the beginning of your line in anticipation of a double-click. This strikes me as a driver error, but I'm not holding my breath for Wacom to fix it.
