Yeah Web King I think this problem seems to be happening with me too since I got in to these forums but I thought it'll be all right with time but this thing doesn't seem to be getting off.
When I click on the tab of 'post quick reply' the thread starts processing its way up and the status bar shows 'done' but all I can see is a blank page. I'm only able to see the thread again when I put the cursor on the address bar and click 'enter'.
Not a big problem to deal with but just a little annoying I guess.
