You really need to upgrade.....
98 is seriously crippled.
The logical thing for you to do is upgrade to 98/SE and then install the UnOfficial Service pack 2.
There is NO service pact for old original 98.
What you should be using though is I.E. 6 SP1.
You can get that from MS on a CD.
That's the best way to install that.....I do it all the time for my customers.
Then stop using I.E. all together and start using Mozilla Firefox 1.5.
That's the best browser you're likely to find anywhere. Safer than I.E. and faster too,
with a great pop-up blocker and super download manager.
Good Luck,
