I made a thread here at the end of 2015 about a few recently-saved files getting corrupted. If you can get it working, great, but for now, this bird flies solo. It's possible it's only the connector cable that's at fault. Hooking up the Cintiq to another machine, and having it act as a second display with stylus input, doesn't seem to work anymore, but it has in the past.

After some testing, it's likely a physical/hardware problem, not software. I never use touch, and only noticed the problem recently, when I toggled it on for the first time in forever. The capacitive touchscreen detects phantom finger-taps, so you'll probably want to toggle finger-touch off.I've gotten used to it, and the stylus mode is fantastic otherwise. (I had a cheapo wireless keyboard/touchpad 2-in-1 combo on hand for this.) The bug will pop up every couple days, or hours, or weeks-it's hard to predict. It's quick and easy to fix when it crops up, though: hook up a mouse to the Cintiq, and use that to restore the tablet's settings from a backup file.

Driver updates haven't patched it so far. This bug has been present since the day I got the tablet from Wacom, in 2015. The only issue with this mode is a well-known Wacom bug which can leave the tablet temporarily unresponsive to stylus input.

The stylus/drawing tech works very well in general.

These go for around $1,500 used right now, but I'm asking for $699, because of a few of problems: See Wacom's product page for full specs: It's the second generation of Wacom's standalone portable Cintiq machines. This is a drawing tablet and computer in one.
