Apple Power Macintosh 9600 - Manual (Page 145)

You see a message that your application program can’t be opened because a file can’t
be found.
Macintosh programs designed specifically for the PowerPC microprocessor
(also called “native” applications) use special files called “shared libraries.”
Any necessary shared libraries should be installed automatically when you
install these special Macintosh programs.
Follow the directions that came with your program to reinstall it. If the
shared library is still missing, contact the software program’s manufacturer
for assistance.
You experience problems using an older Macintosh program.
Some older Macintosh programs are not completely compatible with
Macintosh computers that have the PowerPC microprocessor.
m Open the Memory control panel (in the Control Panels folder in the
Apple [K] menu) and turn off Modern Memory Manager.
m If that doesn’t work, contact the program’s publisher to see if an upgrade
is available.
A window has disappeared.
m Another open window may be covering the one you’re looking for. Move,
resize, close, or hide windows until you see the one you want.
m The program the window is associated with may be hidden. Choose Show
All from the Application menu and then click the window you want, or
choose the program from the Application menu.
