Sigh. I'm glad that the disappearing water that I saw, or didn't see, the first time I used the official 1.23 client appears to be a fluke. What's not a fluke, though, is the inability to hear streaming audio. A friend had invited me to hear a singer, and I was looking forward to it--but I couldn't hear it, and wound up leaving--a darned shame, that.
(And I forgot again that it would forget the custom resolution for photos saved to hard disk I'd set up, darn it...)
