Constraining cursor to a window

[Danny Baldoni]

I'm currently developing a project using multiple windows.  Combined, these
windows cover the entire screen.  What I'd like to know is whether or not
there's any way I can restrict the movement of the cursor so that it can
NEVER (unless I release it) move outside the boundaries of one of those
windows.

Any help would be much appreciated.
