I'm trying to make a free drawing program with c++ builder and graphics32 component.

Usually people use mousedown, mousemove, mouseup events to make this kind of program but it doesn't work well when I tried drawing with a tablet.

I find out mouseup event occur twice when the tablet pen isn't recognized well, so the mousemove event that draw pictures using lineto while mousedown occurs is not executed.

My question is

1. Are there any events that I can use instead of mousedown, mousemove, mouseup for drawing on Bitmap->Canvas?
