Some users have asked if there is a way to prevent switch-launching between
floppies on a floppy-based system.
The "Technical Introduction to the Macintosh Family" states: "You can
prevent this switch-launching by holding down the Option key when you start
the application."
Actually, switch-launching is either prevented OR allowed by this procedure,
depending on the kind of disks in the system.
Hard Disk Systems
-----------------
Switch-launching is generally PREVENTED in a hard disk system. To force a
switch-launch:
1. Hold down the Option and Command keys while opening an application.
2. Set the Finder Flags for the application to "Always switch-launch" (Get
Info on the file using ResEdit).
Floppy Disk Systems
-------------------
In floppy-based systems, the system generally switches to the System files
on the diskette that contains the application being opened.
Holding down the Option key while opening an application on a floppy-based
system will NOT prevent switch-launching (as is incorrectly stated in the
"Technical Introduction to the Macintosh Family".) Therefore, to prevent
switch-launching to a diskette on a floppy-based system:
1. Remove the System Folder.
2. Place either the System file or Finder -- but not both -- into another
folder, or at root.
3. Use MultiFinder, which prevents switch-launching (if there is sufficient
RAM to support both MultiFinder and the applications).
