Thank you, thank you, thank you!
Thank you, Kamran, for posting the question with a very appropriate subject,
and thank you, Greg Maxey, for answering it! I had tried everything I could
think of, including moving my buttons with hyperlinks onto the web toolbar in
hopes that it would stay docked where I put it, but it still jumped to a new
row. So, I put the hyperlinked buttons back where I had them originally and
started searching all over the internet to find out how to disable the web
toolbar. All I found was "Show only Web toolbar buttons," which is exactly
the opposite of what I wanted. Just when I was about to give up, I stumbled
onto this discussion group website and found my answer immediately. Although
the solution implies that it is for use in Microsoft Word, I successfully
used it in Microsoft Excel.
