- Are you quitting applications in the reverse order of launching them? Each
- program takes up a (somewhat) sequential block of memory. For example...
-
- System- 1500K
- VersaTerm-800K
- Microsoft Word- 1500K
- Note Pad- 20K
- Aldus PageMaker- 2000K
- Solitaire- 256K
-
- Assuming you launched the applications top to bottom, you would use about
- 6076K. If you have an 8 Meg machine, this leaves you about 2126K free. If you
- quit the applications in the reverse order, you should go all the way back to
- about 6692K free when you got back to the system level. If you quit ones in the
- middle of the pack, you do not add to the largest free block. Rather, you form
- newer blocks of free memory. Even when you quit all the applications (in a
- different order), your largest unused block still may not be 6692K, since for
- some reason, blocks which are suddenly adjacent do not always unite.
-
- If, on the other hand, you are quitting applications in the reverse order,this
- example is moot, and something else is eating your memory... :)
