hi,
when i use a seprate graphics tablet in speed grader the ink is offset (about 1 cm) from the tiny paintbrush that appears. this makes marking students' work using this method very difficult to do (in a professional way). you can do ticks but if you try to write a formula, forget it.
The tablet is linked to my windows pc via usb.

i did a search on this and other people have commented on it.

does anyone please know why this is happening? yes, i know you can download the students' work and mark in pdf or word but that is slower.
thanks,
david.
