The good folks of the OS X community have been hard at work (or not, depending on how easy it was to do the updates): new Panther-compatible versions of BitTorrent, GPGMail, PithHelmet and FireStarter FX are now available. Still no word on iComic though - the supposed fix does what it says it does, but it's not quite enough. Never mind, now that you can double-click to open apps like Nicotine in X11, who could ask for more?
Update - iComic's fixed too.
