In handwriting mode the stylus is recognized for a short period of time so you get a partial line and then the screen stops recognizing the stylus probably thinking it is invalid input.
Using a stylus is necessary in order to be able to place highlighting accurately and for the handwriting features of the i62HD.
Please let me know how I can go about getting this corrected.

Hi,
the IR Multi Touch technology of i62HD was developed to scan for thicker objects (like your finger e.g.) near of the screen. Just imagine a net of invisible IR rays near of the screen surface. Here you can see the the size of the raster of the IR LEDs:

Boox is just calculating coordinates of your fingers based on interrupted rays.
Just try out a pen, which is similar to a finger
