Alrighty.
First of all, might I suggest looking at an upgrade to Windows XP soon? As Microsoft have decided to stop support for Windows 95/98/ME, so not only are these operating systems out of date, but they will become even more vulnerable very shortly with the amount of spyware/malware that can be recieved due to them not being upgraded.
That being said however, I've once had this same problem long long ago and know it is fixable but unfortunatly cannot remember how to do it off the top of my head (and don't have access to a win98 machine).
However...I have found this guide to help you fix this issue.

Good luck! and let us know how it goes!
