Hi Alan,

--------
Fabio, it might have to do with what your middle button is programmed for. I use mine for a 'double click'. When I hold the middle button, the TAB key is ignored.
-------

With this configuration middle button driver send
- left down && user
- left up && driver send this immediatelly
- left down && driver send this immediatelly

and then VFP do operations like a left double click.

I configure middle button like a MIDDLE BUTTON;
i want a MiddleClick event.

Why Middle button is not equal to other mouse button ?

Fabio
