Using System 4.2 and Finder 6.0, you may find that when using the AppleShare
workstation software you get the error message "There isn't enough memory to
work with CS Server 20" at startup.
You probably need to increase the MultiFinder partition for the Finder.
To do this, select the Finder icon and choose "Get Info" from the File menu in
the Finder. Set the Finder's partition to something other than the default
value of 160K (somewhere around 320K should do it).
The partition generally needs to be increased to deal with many open windows,
large DeskTop files, and large directories.
