I ran into this, too. My first thought was to change width to auto, which seemed to work fine for any skin no matter how wide or narrow the post area and also for PMs but then I tried it in IE and discovered that, without a specific pixel width declared, IE does not display a scrollbar and merely pushes the post area wider.

What I then did was go back to using an actual pixel width (which I also discovered needs to be figured out individually per skin or things like CENTER tags do not look centered) and then added the conditional around class shown below...

<div id="post_message_$post[postid]" class="someclassname<if condition="THIS_SCRIPT != 'private'"> hidemsg</if>">$post[message]</div>

Note, that I already had a class in there so I wrapped the second hidemsg class in the if conditional to add it in only if not in a "private" area. I cannot take credit for that conditional, btw. I found that on the joindays hack because it also does not work properly in the PM area.

If you do not already have a class in there, it would look like this...

<div id="post_message_$post[postid]"<if condition="THIS_SCRIPT != 'private'"> class="hidemsg"</if>>$post[message]</div>

I'm not sure if this is the best way to do it but it works.
