Yes, probably it's a setting, but where is it stored? In the registry? Which key is it? Or are there additioonal registry files?
HKEY_CURRENT_USER\Software\Nero\Nero 9\Nero Burning ROM\Cache\NetDrives from 1 to 0, but it had no effect.
So the qustion is: which key is correct, and is it interpreted at all by Nero Express? Man, how I hate how Nero tries to limit every important functionality of the software that came with the writer just to sell the "full" product (which I won't buy, there is other free software performing well without tricks like that...)
