James amazing WB, I've got it working. But there are some problems with the install: 387 files failed when copying. I guess you should run first a command to unprotect them all (protect dh0:#? +wd all) as I did later.
Also the menus should stay without holding the mice button (MagicMenu, Usage, "Smart Select"). Also, dunno why sometimes opening the drawers as listers they aren't shown, so I've got to change to see as icons and then again to lister and then I can see them.
Awesome the Mac Like Dock
. Incredible how you find OS4 programs that can run on OS3.9
Edit: Also great the AddMenu program, that lets you have a Reboot on the Workbench menu (like ShutDown on Workbench:System, but this as icon-script).
