It's wierd how this works.
- I posted in EE. Returned to the EE forum and my post was there, but not "new" (good)
- I went back into the thread and did a quick edit. I returned to EE and my post was there but marked as "new" (not good)
- I clicked on the "new" icon and entered the thread. Read my post and then hit the "Everything Else" link at the top of the page. This returned me to EE and the thread was STILL marked with a 'new" icon. (not good)
- I hit refresh, just to make sure, and it still had the thread marked as "new" (not good)
- I hit the "new" icon, entering the thread again to read my post again. I then clicked on teh "Build your own arcade controls forum" link, returning me to the main listing of all the forums. The EE forum 'diamond indicator" was blue, indicating that there were new posts in that forum. Of course, the newest post was mine, which I had read at least three times at this point. (not good)
- I clicked on the "Everything Else" forum and entered the forum. The thread STILL had a "new" icon next to it and, of course, my post was the newest thing in it. (not good)
- I clicked the "new" icon again (third time?) and read my post one more time (yawn). I then clicked the "Everything Else" link directly above the thread and returned to the EE forum. FINALLY, the "new" icon had disappeared from that thread (good)
It's clear (from this example and others) that doing a quick-edit of your post can cause the 'new' icon to reappear for your own post. However, the resulting series of clicks on the "new" icon that did NOT eventually mark the thread as having been read are... odd.
Well I saw the same thing today with the "new" problem. I was the last one posted, but it still showed new items in the forum even though there weren't any. I don't think that's related to the client side, isn't that all stored in the database?
