Ah, those icons.. I see. Best solution for everyone involved would be if you upgraded to a current browser (Opera, Firefox or IE 7 would do).
The problem is due to the fact that IE 6 doesn't understand 24bit PNG's with an alpha channel. I used regular transparent gif's for the forum icons on the index page, but unfortunately couldn't get it to work with those "user online status" icons.
I'll try to make it work later today for IE 6 users. I don't have that version anymore, but there's supposed to be a fix I can implement... Anyway, thanks for the heads up.
Okay, and thanks for listening too. I'd rather not upgade to IE 7, so if you can fix it I would be grateful, but if you can't then it's ok.
