Hi Giaguara,
Nope, nothing like that. To be honest, the more I use Leopard, the more errors I'm starting to see. My iTunes would no longer sync with my iPod, so I had to do an OS backup and restore to get around that problem. Entourage periodically bombs out for no good reason, other applications also periodically crash whereas they didn't before I moved to this OS. In terms of config, nothing has changed from my previous OS (i.e. I haven't modified any settings), so this really does look like a Leopard problem, and I'm beginning to regret more and more moving to the latest Mac OS instead of waiting for it to be a bit more stable. My whole reason for moving from Windows to Mac was stability, and my move to Tiger was a smooth one. I hope this isn't the sign of a downturn in Mac s/w quality control i.e. the users become the beta testers, as they do with Microsoft s/w
