Hi,
GFXTablet it’s an nice possible for have an huge Touchpad,
with adding left and right mouse"key" at bottom.
Really well for Grandy and Granpa 
but just need mousekey’s and doubletouch-recognition
maby add by sliding down (or double-touch and scrolling down), the scrolling the page …
maby for both systems, linux and WinNT, because Reactos it’s coming…
with it it is really easy for operate an computer if they have no money for an new and modern Touchscreen with the money of pension with a tablet can make much more and helps much more …
best regards
Blacky
