I don't know why nobody responded to this. At least, I don't see any responses.
Here's the recommended solution: Don't use Internet Explorer _at all_.
*** Use Firefox. ***
Safari updates, if I remember correctly, are only available on OS X 10.3 and 10.4. So the Safari you're probably using on 10.2.8 is old.
A few friendly suggestions:
1. Upgrade your memory to _at least_ 384k. Get a 256 mb or, better, 512 SODIMM. Be careful to buy from a Mac friendly site. Get memory compatible with your particular Powerbook. I've had good success with www.ramjet.com
is also good. Your computing experience will be vastly improved.
2. Consider upgrading to 10.3 or 10.4 after you get more memory. I think you'll notice snappier performance and more reliablity. Go right to 10.3.9 (or 10.4.2) before you do much, especially if you have external Firewire drives. ALWAYS disconnect Firewire drives when upgrading your OS.
3. Google for a program called Broadband Optimizer. Try "broadband optimizer os x" in Google. It should improve your transfer speeds.
