Bug? [solved] Strange Y value returned by the Panel_Touch event

I begun to 'learn' graphics in B4i and notice strange Y values returned by the Panel_Touch event.
Attached the test project, you'll see that the drawn vertical coordinates are not equal to the finger position. The values are smaller than the expected ones.

There is no project attached. I'm guessing that you are not reinitializing the canvas in Page_Resize.

Oh miracle, this was the problem .
