Reported bugs in Release 3.0
Floppy-disk ejection
A bug with the workspace prevents floppy disks from being ejected when some Dock-extender programs are automatically launched from the user's dock. The solution: Launch the Dock extender manually, once the workspace starts up, rather than at login.
DOS and Mac file systems
Files stored on DOS- or Macintosh-formatted floppy disks occasionally disappear or are unaccessible on DOS or Apple computers.
AppleShare
Doesn't work with large networks.
Mail attachments
Attachments stored in mailbox folders under Mail 2.0 sometimes disappear when viewed with Mail 3.0.
