You must have missed the comment above... we don't want to force the toobar onto 2 lines as in some cases the width is wider for the editor on other pages. so the drop downs can fit on the first line.
Also if we add a style to the page of
<style type="text/css">
.CuteEditorDropDown {width:71px;}
</style>
so just increasing the width of the drop down by 1px the panel flows onto the next line... so can only assume it's an issue with css and widths?
