I just created a new thread (msg:29409.1) but it won't mark as read.

(Created in light mode, viewed it in both light and regular)

Going into thread options and manually setting it to 1 of 1 worked though.

Getting the same problem with my two poll test threads as well.

Working now?

 

At least there is no reason for it not to work.

Still showing as 6 new and 8 new respectively!

And now?

 

(You'll have to click on the threads again to mark them as read.)

Yay they've gone this time. Good work, stout fellow, cup of tea.

that's fixed very well - it took out the post secified and all related posts, leaving the original thread intact and creating a new one for the off topic post and it's replies, oh and left links to where all the moved posts had gone

all exactly as you expected I have no doubt, but very impressive
