It's been going on for a while and I've learned to live with it but out of the blue on irregular intervals and at least twice a week my Xencelabs medium pen tablet seems to have a live of its own by frantically moving the crosshair, pointer or brush (depending in what program I am) and activating menu's or opening and closing things as if it's randomly controlled by someone else. It takes maybe just 2-5 seconds, the process is like a fast forward motion and when I remove my hand that holds the pen of the surface of the tablet it just keeps going. After that, unnecessary windows are open, commands that I do not want to be activated are activated, the program I use has been minimized or the window shifted that it's half on the screen and now just before I post this the program I was using just closed without saving the work I was busy on (a 3D model). I lost a 3 hours of generating content whereby I thought to address the issue now. In the past I have been able to get back to the normal state just before a 'burst' happened by pressing ctrl-z (in Photoshop whereby random paint strokes or lines where appearing) but it's not always been possible.

The tablet and pen work fine for the rest but these 'bursts' are quite annoying especially when work is lost. I tried to record my screen in the past at irregular intervals but have not been able to record such a 'burst'.

Any advise or any one else that has experienced this?     

Once I disconnected the wireless dongle and used a hard-wired connection the jumping cursor went away. Just my two cents.

I have just received the pen tablet bundle. Everything worked perfectly including setting up the driver. However, 5 times within the first 4 hours of use the cursor started randomly jumping around on the screen while randomly clicking things. It would do this for a few seconds and then return to normal. While it was happening there was nothing I could do to stop it. I have gone through all of the tests in the pen diagnostics article and everything seems ok. I can't discern a pattern in the occurrences, each time I was doing a different thing on the screen. It doesn't seem related to any actions like touching the pen to the tablet or pressing the buttons. I have reached out to customer service but wanted to also comment publicly here in case anyone has a solution.

That's crazy. I've had the exact same thing from the beginning of owning this tablet. I figured it would just be me. When it starts, even when I put the pen away from the tablet, it just goes and goes causing all kinds of havoc on what I have open at the time. Unfortunately it's completely random, and I'm unable to make it happen to get the evidence so to speak. It might be a few times in one day, or it might go weeks without it happening.
