without ANY other changes to my hardware / software, I used IE 5 to download the iTools installer and let it use Explorer as the browser to connect to the iTools site and....
1. I'm out of the endless download loop, and
2. Can connect to my iTools site with both IE and Netscape after it was initially configured with IE.
Conclusion:
IE is clearly becoming the browser of choice for more and more web based tasks.
Smaller, faster, better
