here we are, after months the same problem never solved.
I just want to write few words to a simple analyzing made in last days.
As I said, I use Photoshop and Wacom tablet and this problem was solved by java updating then after the last apple updates the problem come back again.
If i hide the dock I don't know why but the problem is less visible.
How to make going crazy the cursor, when I need to paint a big area with a big brush (did the same with a simple default photoshop brush) and I move the cursor over the interface the cursors start to blinking speedy and then it will vanish.
I did this test many times, as a user said , there is a OS problem about some service that "refresh" the mouse pointer that sure going crazy and crash.
During painting, I can do that for hours whitout any problem, the problem is somewhere in the OS when the stupid MONTAIN LION had to change the cursors from a brush to the standard cursor.
This is my analyzing, I don't hope that some one reads this a find a solution, but as I said many times I have no problem before mountain lion,this is the worst os never used.
Work with this problem is ... mmm there aren't many words to explain it.
I want to explain to all user that talk about battery, wireless etc that it's sounds like a software problem rather then a hardware problems.
thanks everybody
