Radio's WYSIWYG editor doesn't work with Mozilla

Now that Mozilla 1.0 has been released, one of the things that's standing in the way of using it fulltime is the the fact that Radio's nice WYSIWYG HTML editor only works in Internet Explorer.

This is annoying not only the PC, but on the Mac as well, because even IE for the Mac doesn't support this technology.

Anyone have a nice solution that would work for the Mac and PC in Mozilla without paying more money? I know there's at least one commercial Java solution, but this feels like something that UserLand should step up to.
