Mouse Control issues

I need to implement mouse control into a game, I'm not experienced in this area at all!

I've set up a Mouse Control movement object. You specify the frame size you want the mouse to move in, which is fine...but then the frame does not shift as the screen scrolls, even if the object is set to not 'follow the frame'.
Is there any way I can make the area the mouse can move within scroll with the screen?

You can make a custom mouse movement. Here's an easy one:
* Start of Frame
> Hide the Mouse Pointer

* Always
> Object Set X Position to Xmouse
> Object Set Y Position to Ymouse

make sure you set the hotspot of the object to its center! :D

Ahh, brilliant, I didn't know you could set objects directly to the mouse coordinates!
Thanks : )
