Yeah, Sherlock acts like crap for me. Channels are there one minute, gone the next. Delete the preferences and they're back, then gone again five minutes later after I quit and re-open. I never actually used it because it was new to me when I got this iBook. I still haven't used it, because it's annoying to see disappearing channels. I received responses on various forums that Apple was ditching it. If anyone knows anything about this, I'd be slightly interested. It looked semi-useful...does anyone use and like Sherlock?
