Hello and thanks for your answer again.
yesterday my tablet show a exclamation icon on the device manager when i install the drivers
and do not work, but now i reinstalled windows one more time after format my hard disk, and drivers seems to work fine, with good sensibility in photoshop cs3 but do not work in photoshop 4. This is enough for me by the moment, while genius release new drivers for Windows 7. This was very strange for me too, im sorry about the troubles and thankyou for your help again.
