Stylus pointing not working like it should while drawing on pocket pc

I'm making a signature application for my pocket pc. It works but when I test it with the emulator (mouse) it works like it should but when I try to test it on my device (stylus), the line that I draw is a little bit off where I am actually pointing too.

Anybody got an idea what it could be? Tried to find a solution on the internet but still nothing came up. Personally, I think it isn't the code but the pocket pc.. a configuration or something...

My code:

PictureBox1_MouseDown:

 x_md = e.X
 y_md = e.Y

PictureBox1_MouseMove:

 x_mm = e.X
 y_mm = e.Y
 Dim g As Graphics = Graphics.FromImage(bit)
 Dim myPen As Pen = New Pen(Color.Black, 2)
 g.DrawLine(myPen, x_md, y_md, x_mm, y_mm)
 PictureBox1.Image = bit
 x_md = x_mm
 y_md = y_mm

x_md, y_md, x_mm, Y_mm are all int16

King Regards

Not related to your drawing issue, but hopefully you are calling g.Dispose() at some point or you are going to give the .NET garbage collector a heart attack. – Bradley Uffner
I didn't add the GC yet.. It needs to work proper before I do anything further like GC'ing.. – user3360972

You're drawing on the image, but the mouse coordinates are on the picturebox. You can either draw on the picturebox or adjust the coordinates x_mm, y_mm to the offset and relative scale of the image.
