I'm back home now, and I see IE8 remembers me when I look at the Fleamarket. Using IE8 at home the ad descriptions disappears when I click on the ad.
I realize the Fleamarket is separate from the forum and you can't correct the problem, but thought you might want to know that all the problems with the Fleamarket have not been corrected.
BTW, when I click on an ad using Chrome, I see the full description.

I don't think the problem is browser specific. It's more of a problem of getting old "stored" information out of the browser that is causing you trouble.
If at all possible, you really should move ahead to at least IE9...as mentioned IE11 is out. Webpages are indeed written for some of the more prevalent browsers and thus some features might not work properly the farther out you get. I wouldn't make the jump all the way to IE11 but do one at a time over a period of 6 months or so.
