Hi,

Yes, drivers are the current WACOM drivers. The pen does show pressure on Wacom Tablet Properties -control app.

Now I found that I had to enable 'Use Windows Ink' checkbox on Wacom Tablet Properties / Mapping page. Otherwise there will be no WM_POINTER... messages at all. However, this is unfortunate, since this causes drawing to start with a couple of centimeters long straight line before I can draw any curves. Anyway, this gets the IsPointerPen() true!

I also found that:

						if(ppi.penMask & PEN_MASK_ROTATION)
							pen_pressure = ppi.rotation * M_2PI / 360;

should be

						if(ppi.penMask & PEN_MASK_ROTATION)
							pen_rotation = ppi.rotation * M_2PI / 360;

Then the thickness works based on pressure.

Best regards,

Tom
