Steve, nto sure if this will be any help, but the mouse wont go outside of your
View boundaries. So if you have opened your own view, that is not large enough
to support overscan then this will keep your mouse from going out to overscan.
This is talked about, only slightly, on pg 52 of the enhancer softwaare manual
that came ouith ver. 1.2.
Hope this helps, `
