Yeah, SL is so slow these latter months (almost a year, now I realize), that I've been using it as screen saver, no more. Simply I can't do nothing: When I move my av is like a slow-motion movie. And well, concerning my system, it's not pentium definitely: A Sony Vaio 4GB Ram, ATI Radeon, etc.
A nonsense, fellows.
Somebody should fix this, because I can't visit my beloved Victorian places with dignity
