this happened most of yesterday afternoon, but i was too busy doing real work to raise this defect. I'm using IE6. When i click to ANY reply button in a thread the screen flashes but no reply box is to be found anywhere.
As for logging in, the top box doesn't work. the user name box allows text input, but there is no masking on the password box, and it doen's recognise it as correct. I logged in perfectly fine using the full log in page.
