Hi all,
Having some difficulty getting this to work. I'm trying to create a click and drag scrolling system using the mouse. Where you simply click and hold the mouse, and the screen moves opposite to where you move it. Similar to most touch phone applications I guess.

Aha, thanks Nivram. How did I miss this one? I searched your website a couple of times...
Thanks again, it's perfect!
EDIT:
Hang on, it's not quite perfect. It seems to stuff up if I make the frame size any bigger... Any idea why this is?

+ User clicks with left button
-> Set DragX to XMouse
-> Set DragY to YMouse
+ Repeat while left mouse-button is down
-> Center display at X = ((X Left Frame+X Right Frame)/2)+(DragX-XMouse)
-> Center display at Y = ((Y Top Frame+Y Bottom Frame)/2)+(DragY-YMouse)
(credit to RedEnchilada for coming up with that)

Don't know. Apparently (s)he was formerly known as "RedEchidna", if that means anything to you. To be honest, I can't keep track of all the people on here and what they do (especially all the Andys).

Thanks Sketchy for your infinite usefulness.

Like me! There are a fair few Andys aren't there?

Yeah, like you. And AndyUK. That might even be all of them, but it's still enough to confuse me...
