I have a strange problem with GrafX2 on my PowerBookG4 with MorphOS 3.17.
If I try to use "Pick brush" (press key B), the application works veeeeery slow. Too slow for cut a brush. When I move mouse, horizontal and vertical lines move terribly slow.
If I turn on a zoom (press key M) and move mouse quickly, the application also works slow, position of the mouse is updated with very low frequency.

I would like to know if this problem occurs only on my system/device. Could someone check if is able to reproduce the problem?
