Remote Scripting - Win95

Windows version snobbery aside, I get paid so I can't complain.
I have an intranet site running merrily away and using Remote Scripting for a number of purposes.
All very well in our Windows NT offices, but I get trouble when our Windows 95 (yes, I know...) offices access the site, despite both running the same IE version (5.5)

"Object doesn't support this method" or "whatever" is null or not an object."

I've searched for Remote scripting requirement but found nothing that might suggest these problems are the natural state of things.
Anyone else experienced difficulties remote scripting for Win95 client?

Thanks for reading,
