IE6 20 Cookie limitation

I’m writting a browser application in JavaScript. I wrote most of it when I was running WinMe. I’ve recently switched to XP Home and now Cookies are disappearing. I thought it was date related, but that’s not true, some created this morning are now missing.

document.cookies.length is well below 4k.

I’m running Version 6.0.2800.1106.xpsp2.021108-1929

It seems that I can only write 20 cookies per document now. When I write the 21st, the oldest dissapears. Does anyone have any idea how to get around this new “feature”? I looked thru the browser settings and don’t see anything obvious.
