Subject: Re: Memory question///... 
Status: OR

What you describe is the infamous (known) memory leak.  Every time you
switch from one app to another (or when it activates a new active one,
and deactivates the oldest one, I'm not exactly sure), some amount of
memory is 'lost'.  This loss is rapid at first, then slows down over
time, but you will notice performance degradation as the amount of
free memory decreases.

It is recommended to do a reset when free memory gets below 70% or so,
but that only makes sense if you have nothing significant stored on
the machine.  What I use as an indicator is when I've lost more than
50K, I generally do a reset (that's usually between 1 and 2 weeks of
use for me), unless I just can't face resetting all the settings that
get lost (see below).

Doing a reset (I like to put a non-editing app in the forground, like
the file manager, then push the reset button, just to make sure I
don't trash a document or loose changes) will free up the lost memory,
and your data will be intact.  Take note that all the settings for the
World Clock (including things like the name and location of your 'home
city') are lost, the system default document (rather than the last
document used) will be opened for the Address Book/Notebook/Calendar/
Pocket Quicken, the views in the File Manager will revert to the
system default, and all the numbers in all the forms of the form
manager will get reset, and probably some other things I haven't
noticed yet.  But other than that, you can resume work as normal :-).
