Apple Power Macintosh 4400 - Manual (Page 105)

If a DOS document is displayed incorrectly, or you see strange codes or
characters in the document, try one of the following:
m See the information that came with your program. Your application
program may have special procedures for opening and saving documents
with different file formats.
m Try opening the document in another program.
Note: Some characters that can be displayed on the Macintosh are not
accurately displayed on DOS computers, and vice versa.
For more information about working with DOS documents on your
Macintosh, see the “DOS, Windows, and Apple II Files” topic area of
Macintosh Guide, available in the Guide (h) menu.
You see a message that your application program can’t be opened because a file can’t
be found.
Power Macintosh programs use special files called shared libraries. Any
necessary shared libraries should be installed automatically when you install
Power Macintosh programs.
Follow the directions that came with your program to reinstall the program. 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 Power
Macintosh computers.
Open the Memory control panel and turn off Modern Memory Manager.
You can’t record sound using an external microphone or the microphone built into
your monitor.
m Any time you want to record sound, you need to make sure your sound
input source is set to External Microphone. Open the Monitors & Sound
control panel in the Apple (K) menu, click the Sound icon, and choose
External Microphone from the Sound Input pop-up menu.
m If you’re using your monitor’s built-in microphone to record, use the
Monitors & Sound control panel to make the monitor’s speakers mute. In
the same control panel, make sure that the sound input is set to the
monitor’s built-in microphone.
