I have a base machine & a laptop...
The laptop has hardly anything on it as I'v just re-installed Win7 Basic edition.
The screen grab up there /\ /\ has an image of the installed software screen.
For the base machine, the Desktop Manager is version 7.1 and the Os says ..." Blackberry Device Software V6 for 9300 Smartphone"..
This is the Laptop /\ /\ /\ screen..
Puzzling isn't it ?
