Hiding and showing windows on the desktop

You can hide all windows except those of the active program by choosing

Hide Others from the Application menu.

The other programs remain open even though their windows are hidden.

When you switch to another program, its windows become visible again.

If you want to see all the open windows, choose Show All from the

Application menu.

Using “native” application programs

Your computer is compatible with nearly all application programs intended

for use with Macintosh computers. But certain programs are designed

especially for computers with PowerPC microprocessors. (These are

sometimes called “native” applications.) You’ll find that these programs take

best advantage of your computer’s speed.

Special memory requirements

Some native programs may be slightly larger than other programs and may

take up more memory. If you find that you are running out of memory when

you use programs designed for PowerPC microprocessors, you can use space

on your computer’s hard disk as additional memory. This feature is called

virtual memory. Your computer was developed to take advantage of the virtual

memory feature, and comes with virtual memory turned on. For instructions

on how to use or increase hard disk space as memory, see the “Memory” topic

of Macintosh Guide, available in the Guide (h) menu.

You can also add more memory to your computer, as described in the Te ch n i c a l

Information booklet that came with your PowerBook.

Shared libraries

Native programs use special files called shared libraries. These files help the

programs to run more efficiently, and can be used by more than one native

program simultaneously. Any necessary shared libraries are installed

automatically in the System Folder when you install native programs.
