This morning Apple released Safari Beta 2  which has a raft of improvements, including the tabbed browsing feature from some other unofficially released builds. The build of this version is reported as 1.0 Beta 2 (v73). I quickly took it for a spin this morning on Macromedia’s site  and I think this release has solved a lot of the problems folks were having, it even apparently allows remoting to work! Im going to do some more testing, but if you do any Flash work at all and like Safari. You should certainly pick this version up.
