Editing a reply today, the screen kept “resetting” on me - back to the main page with all the forums listed. If I clicked the BACK button I could get back to the edit in progress (without losing anything), but it was very aggravating. Happened at least a handful of times.
Another thing I’ve seen - and it could be a local network issue - is the “wait” pop-up appearing at the top of the page. If you hit the space bar you can blow through it, but it’s annoying.
