If you use the TinyMCE editor then there is a 'code' button that is specifically for the job. That one works. The one on the QuickTag buttonbar doesn't really do such a good job. it used to but something seems to have gone screwy. I'll look into it.

The problem with long, unbroken lines or erroneous text pushing the width over the right hand boundary is one of the vagaries of HTML sadly. And the only other way to edit is in the database.

Try opening up your skin CSS file and adding this to the:

#sforum .sfposttable td.sfpostcontent {

directive:

overflow: hidden;

That should help althoug it depends what HTML tags it has around it.

No there isn't. Perhaps that's something we will have to deal with at some stage.

V3 does come with a way of mass removing old, reduandant topics though
