Discrepancies between HTTP versions should have nothing at all to do with your problem. It is perfectly fine to see differing versions are you're noticing.

It's certainly possible that the user's security or cookie settings are rejecting the cookies before they even get a chance to. Some naive users will read on one site that cookies are evil, disable them, and then forget about the whole concept a day later. It could be any number of things. I'd check to be sure everything it's enabled in their browser (security settings? "advanced" settings?), and failing that, see if you can get at the raw HTTP traffic (or at least what the script is reading from the browser and what it is sending back) and look for any anomalies.
