Yay! Mozilla now has a native OS X UI. It’s still kinda ugly in places (noteably the buttons top right), but it’s Aqua enough that I can stand to switch from IE at home.
Windows 2000 was better behaved today. It didn’t flake out until around 16:30, when IS helpfully set things up so I could log in to the domain at work. When I logged in, EXPLORER.EXE would crash with some horrible error, and the desktop would fail to appear. The solution turned out to be to blow away all my preferences and files for that account, and let Windows re-create it empty.
