Forum Posts extending beyond page width

Strange, but every so often when a member copies and pastes a post into the forum. The text extends beyond the window frame of the page. The Sub menu that says Hide, delete, edit etc. The edit is off the screen and inaccessible. Anyone else run into this and is there a fix? It is in a Private Group Forum. Looking at the post in database. I see one <div="floater-50" /div>

Bump

Yes, that is because they paste in the page code as well.  I have this on my site at times.  I usually go in and try to fix it if it is not too much work.  Images pasted in as well can extend the width.  I have not played with trying to change the forum css to handle this as it does not happen that often on my site.  I am rather busy with a few projects to spend a lot of time on it.  One thing you want to do is to set some maximum widths so that the container the forum posts sits in cannot go any wider than the max width size. 

TY GG,

I know where to find the post in the database and can edit it there. Just not sure where to put the code to use to set the max  width for the container.

Just a follow up. Well, what I wound up doing is deleting the post. Recopying the text from the source and then creating new post with the forum under same title without using the HTML. Must be some place to put that container restriction in the Tiny MCE to eliminate future issues. Thanks for the push GG, you did help me think of a quick solution.

I have not styled the forum so can not give details until I take a look, Heading out the door for work so no time now.
