Wow, y'all. I'm familiar with that banner / ad cover thingie, but I'm totally not seeing it. Only on rare occasion and it's been a long time.
Hmmmmmm. Maybe a mention in the site feedback room?
They're probably using old fart threaded mode.
We used to have the problem with large pics, they fixed that, but it still happens with long urls or run on sentences, or if one is viewing it in threaded mode, when the thread gets long the ads overlap.
Things seem to have settled, maybe it's time we bring it up again.
Here's the original thread
where the problem appears, switch to threaded mode to see it.
Also the reply window can be dragged too big and it will overlap the ads.
