I always add my blog posts using source view. If I come back and re-edit a post at a later time the following code has been added.
<p><span style="border-radius: 2px; text-indent: 20px; width: auto; padding: 0px 4px 0px 0px; text-align: center; font: bold 11px/20px 'Helvetica Neue',Helvetica,sans-serif; color: #ffffff; background: #bd081c no-repeat scroll 3px 50% / 14px 14px; position: absolute; opacity: 1; z-index: 8675309; display: none; cursor: pointer;">Save</span></p>
This code is added after each edit so could be repeated three or four times. It's not a particular problem as I'm just deleting it but it does seem odd and was wondering if this is a normal function?
