The region appearing around the Slashdot image is clickable to return to the front page, however the image itself is not a link. I don't know if this is easily replicatable on your end, but I would be happy to snapshot the code and upload it to this bug report, or host the file on my own site for download.
Please advise what information you need if I don't provide it here.
Has been happening at home, school and work, using IE7 and IE6 (using 6.0.2900.2180.standard xp sp2 fare with regular updates right now). Using XP home and Pro, and on AMD and Intel chips, various mobos.
As I said initally, it is only the image itself that is not a link. In the past, this was a link. I like this feature working the way I remember it to have worked.
This should probably be a low priority item, however it does not seem as though it would be difficult to remedy, unless I'm the only one complaining, in which case ignore it, but I'm probably the only one motivated enough to do something about it right now. I tried looking through the open bugs reports right now, and couldn't find this issue.
