Actually, this isn't true.  The problem arises when you restart your Mac or run
an application in a non-Multifinder environment.  The Mac very often becomes
confused about which System it should run, and restarts with the wrong one.
This is the same phenomenon that happens with multiple floppies--the Mac will
start running off the floppy with the current application on it.  Unfortu-
nately, the Mac's heuristic for determing which system to use fails if there
are multiple Systems to choose from.  I had many problems with this while
trying to install the new System on my II (no, I don't use Installer, and
don't flame me!); the computer would restart, come up with the happy mac,
then the screen would fizzle and resolve into the disk with the blinking
question mark.  System 4.2/Finder 6.0 do NOT solve this problem.  The only
solution I have found to having multiple Systems on the same disk is to rename
all but the one you want to run from (by duplicating them and tossing the
original).
