I recently acquired a Lenovo LT1423p, which is basically a poor man's Cintiq. I was running BlackInk on Windows 7 and after installing the DisplayLink and Wintab drivers everything was working fine, but I upgraded to Windows 10 today and I now have a problem where when BlackInk is running (no other programs, though), it tries to map the pen input to my main monitor (which is a dumb ol' Samsung SyncMaster 2343) rather than to the ThinkVision's display. If I tap the Thinkvision, it will map to the ThinkVision for one pen stroke, but as soon as I lift the pen the cursor jumps to the other monitor. Every time I tap the ThinkVIsion to get the pen input back onto it, Windows interprets it as a click on the main display, so if I try to draw I get all kinds of windows opening accidentally on the main display, etc., not to mention half the time when I try to start a stroke I a click on the main display.
Anyway, has anyone else had a problem like this with multiple displays when the touch display is not the main display?
