1. Made the test... happens nothing, i mean in Safari i see a white empty page!
2. My system (OS Tiger) firewall is inactive.
3. Ram 1.25 Gb.
4. Two hard disk - 52 Gb. + 196 Gb.
5. Broadband
6. D-link router DI-704P
7. I connect from work
8. LW version 4.8.1 pro
9. ISP is Fastweb (I suspect that is the responsible of the problem, by the recent law in Italy for protection of software and media copyrights).
10. It's a new problem, I use LW from several years both on Mac and Pc platform.

Thank for help

Marcello
