[X4U] Safari problems

[railfan at telus.net]

My daughter is using my 6 yr old iBook 366SE, with 320MB RAM. She has OS X 10.3.9 
and a cable modem connected via Airport.

When she surfs the web using Safari v1.3.2, after about 10 minutes, the pages no 
longer load. She needs to quit Safari, close the clamshell, wait a few minutes then 
go and start Safari again, for another 15-30 minutes of surfing. She reads her email 
from her webmail and prefers it that way.

I know Safari can be a memory hog, and with only 320 MB RAM, but are there any 
things I can do to stop or atleast mitigate Safari from "locking up"?
