Losing format on edit

It seems that when I go back into a post to edit it (using Firefox 17 & 18, and Google Chrome) I will lose paragraph formatting. For example, what used to be this...

This is sentence one, paragraph one. And this is sentence two.

So let's start a new paragraph, shall we?!


Will become this...

Any ideas? It seems to happen only when I have attachments or linked photos.

Yeah I know - it's really annoying. I just looked and the bug appears to be fixed in the next version of vbulletin. The site could use an update to fix little things like this.
