Hello Joanna,
The problem could be related to some global CSS style, e.g.
<style type="text/css">
body { overflow:hidden !important; }
</style>
that is hiding the scrollbar of the editable iframe element in Design and Preview mode.
You can try to fix the problem by setting the
CssFiles property to point to an empty css file. See this article for more information:
Content Area Appearance Problems.
If you unable to solve the problem on your side, please, provide a live URL to the problematic page or isolate the issue in a sample working project and send it for examination.
Sincerely yours,
Rumen
