Hi ya', MJB.......
You have encountered the stubbornest doors in adventure gamedom, for one thing. <img border="0" alt="
" title="" src="graemlins/woozy.gif" /> You can try standing Bradwen off to the left or right side of the door and moving him one step at a time, laterally, and trying again with each step, until the door opens.
The OTHER possibility is that you have missed something. If you are still stuck after trying this, let us know which walkthrough you are using and maybe we can find another or add advice that will help you out of the stuckness!
Best wishes, Witchen =O)
