I have submitted this question to the Mobile Computing forum:
http://www.techimo.com/forum/t80530.html
For convenience I thought it might be better to have the entire thread in that forum instead of having separate threads in two forums/fori/fora.
(of course this doesn't mean that I think that the Mobile Computing forum is smarter, funnier or in any other way better than your Graphics forum..., I mean, how could it be...)
Thanks for your help
Luigi
