If I click on a member's name, and then on "Find all posts by this member", the links above the posts to the threads (next to the envelope) are there, but they are invisible (just a blank space where I would expect to see the thread's name).

Everything looks in order here. Mozilla 1.6

Fine in IE6 too!

What browser are you having problems with?

Are they white on a white background?

Sometimes that happens to me--no idea why.
EDIT: IE 6 on W2K

Yes, seems it's white text on a white background, it's visible when I mark the link area.

Using IE5 on W2K, maybe moving to IE6 will help, I'll try later today.

IE5.5sp2 and win98SE: same "problem"

Hey, moving to IE6 actually solved it, now the white background has become blue (well I hope it's blue, being a little colourblind ). So the white text is readable now.

Noted however that if I scroll fast, this blue background does not appear for some reason. Have to scroll slowly or do a refresh, then all goes well.

Thanks to all for the help!
