I've tried with Mozilla 1.1 on 3 platforms (Mac OS X, Win XP, and Tru64 UNIX); plus Internet Explorer on XP and OS X; and OmniWeb and Chimera on OS X. It didn't work RIGHT on any of those. However, after writing the earlier note I went off and tried the latest Chimera nightly build, and I now own the full Millenium Dragon pack. I'm not sure whether that's good or bad, since it's really cool but I'm sure that (like 99% of all the other stuff I've bought for Poser) I'll never use it enough to justify the price. But that's what hobbies are about, right? ;-)
