It also seems the mobile skin only has infinite scroll. Not a huge deal, but makes it difficult to get new posts in a long thread.

Yes mobile is IS-only. Best thing is to figure out the navigation in IS. Use the gray nav bar at the bottom of the screen. You can go to first/last or any "page" in the middle.

Any improvement in this area of ads covering the screen? And what happened with the pics being back in a frame? Thanks!

That will not happen if you use the mobile skin...

Also... what do you mean pics in a frame?

Where it says “attached thumbnails” it quit doing that and loaded full pics, but perhaps that’s only a feature in the mobile version. I like the mobile version but just can not deal with the infinite scroll.

Can you post a link to an example post where it's happening?

From what I can tell, there are no more thumbnail pics that enlarge when you click on them. Pics are all full size to fit the screen and resize automatically.

That is correct.

All of my pics still show up thumbnails.

Hmm weird -- how did you attach that?
