easy, u just add
<nobr> before all the content in the layer, then close it with
</nobr>ex
CODE
<div style="width:200; height:300; overflow:auto;">
<nobr>blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah
<br>
blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah </nobr> </div>
and just add
<br> to break the lines in it, so it all isnt one long line
