Hi Josh - sorry to report a bug!!!
When activated the new Cliker ClipArt button caused extra line breaks in some places - blank line in HTML mode, resulting in line break in saved page.
Disabling the button stopped the fault
Sample HTML 1:
<div style="background-color: #ffffcc; width: 228px; height: 145px; float: etc"> <span style="font-family: arial black,avant garde;">Compatibility</span> BREAK INSERTED HERE <span style="font-family: arial black,avant garde;">Requires </span> version 2.8 or higher </div>
Sample HTML 2:
</h2> BREAK INSERTED HERE [wpcol_1half id="" class="" style=""]
Normally there are no line spaces or hard breaks where I've shown BREAK INSERTED HERE.
This didn't occur where "p" or "div" markup was used manually - so lokks like something with WordPress function adding "p" markup
I don't need a fix - only tested the new button, but I know you like to know about any bugs
