Hi

Is it possible to alter mouse coordinates from within a
WH_MOUSE_LL hook proc?

I've tried in vain to achieve this by calling SetCursorPos
inside my hook proc - but while the cursor does move to the
new position, thereafter my mouse gets "pulled back" to those
new coordinates every time I move the mouse.

This may be in part to the fact that once I've moved the mouse
to the new coordinates, I am then returning -1 from my hook
proc, as I don't want windows to continue passing my mouse
data down the hook chain, and on to any applications.

How can I prevent the mouse data from going any further than
my hook proc?
