I have found that the three-pane arrangement works fine for reading messages, but the length of replies and posts, and the odd arrangement of a scrollable text box within a scrollable frame made me want a better way.

When I remember to, is use a new explorer window for posts and replies, so I'm not confined to the frame height. I don't know if this would create any problems in other browsers, but for me it would be great if this were the default behaviour for replies and posts.

Thanks
