With respect to strokesplus_2.8.2.0_x64 on a windows 7 Fujitsu tablet pc (T904).
Any gesture is drawn diagonally offset from mouse position instead of directly under the mouse position. This means that the gesture is off screen most of the time. The diagonal offset is about 1/2 the screen width. I also tried the latest beta version and I still have this problem. Otherwise, it seems to work fine.
