Thanks, Rachel. In Chrome, when I right click on the image of the signature, all I get is the standard list of options produced by my OS, nothing WP related. When I hover on the sig image, I get 2 icons: a little pencil and an X. When I click the pencil, I get the IMAGE DETAILS window with a variety of options, but none that address the issue. In the previous version of WP, clicking on the image gave me option to adjust the spacing around the image so I was able to adjust it that way.
Thanks,
Eric
