I hope no one will be convinced to use the SheepShaver Wrapper instead of an alternative that might be better for them. Obviously, this is not the ideal solution for everyone.I like the SheepShaver Wrapper for the easy way it can be set to this quasi full-screen mode, although I myself never use SheepShaver (or BasiliskII) full-screen. But otherwise I do see little advantages over the regular SheepShaver versions. A simple pre-configured VM could be helpful for some, though.
I hope you will post a thread with instructions for using your prebuilt VM, which avoids all the AppleScript complications that I built into the SheepShaver Wrapper.
