I think I know why it's not working.
I have an h2 heading followed by a couple paragraphs. I wanted to insert an image
before the heading and float it right so the top of the image would align with the h2 heading and the text would flow down the left side of the image (which it does). What I didn't realize was that the image got wrapped in the h2 tag and I've only been selecting the image not the outer h2 text. However, if I insert the same image somewhere else within the run of text it gets wrapped in a p tag and then I'm able to attach a link to it.
The code generated by Tiny:
<h2 style="text-align: center;">
<img style="float: right;" src="resources/magCoverThumb.jpg" alt="ad" width="191" height="300" />Click <a href="http://somesite.com">here</a> to view Past Issues</h2>
<p>Paragraph 1</p>
<p>Paragraph 2</p>
<p>Paragraph 3</p>
