[Re: Win8] That's what I did. Turned off press-and-hold ("Gedrückthalten für Rechtsklick") and flicks ("Bewegungen"). The issue is described here too: http://forum.wacom.eu/viewtopic.php?f=4&t=11787 and no one can find a solution. If you could get it working somehow, you might be on to something.
Well, it just worked for me somehow. I suggest you try disabling wisptis (check for a process names wisptis.exe). Another possible way would be to go into the registry, decrease the minimum allowed time settings to 0 and change the actual time settings to 0 aswell, then reboot.
