'Lag' or Trailing Line
I just did some more experimenting and it seems that if I replace the tip of the pen, it starts to react better, not great, but definitely better.
Again, I'm using an Intuos 3. On the Intuos 2 I was using, if I replaced the tip, it would improve, but I was going through tips every two months or so. That's why I bought the 3, thinking it would be better because I've never experienced this problem with my 3 at home (these problems are all happening at work). I'm not sure which tablet your have or if you have the spare tips that come with it, but that might be your solution.
Also, check your Wacom settings and make sure the "tip double click distance" is set to "Off". That should help a little.
Another forum post suggested not using the stylus stand or holder. It could...not sure that it actually does...damage the stylus tip so that it reacts as if pressure is being applied. My stylus at home is always in the stand and, since it does have this problem, makes me wonder if this is valid....but why chance it...different stands and different stylus.
Good luck and hope this helps!!!
