That wasn't very clear was it?
What I mean is that when the screen is touched in another location, the mouse has now moved. Therefore, a click = a mouse move.
I don't quite understand what you're suggesting this this last comment.

It's actually quite hard to get this to occur and it only happens on the odd occasion. I still feel you need to have it ignore (or not actually change the location of the picturebox) if the mouseclick/mousedown is detected - because I can actually get it to scroll with the mouse button pressed. I played with the 'MouseButtons.None' thingy but didn't get any love there.

I'll have more of play once I have it running on the touchscreen itself and see if I can even get it to happen - may not have to worry about it.
