I know of no cure since MS seems to be pushing for XP to XP communications.
Have you looked at SKYPE?

When attempting an audio conversation in MSN Messenger 6.2 with a friend who is running Win98se, she hears me clearly, but I receive fractured speech from her end. However, all runs well if I use my other networked pc, which runs Win98se. I gather there is an issue in communication between these two OS's? Any comments, or a fix, please?
