If you have 2 or more tabs open to speed things up a bit you must remember to refresh your browser especially when you return the html back to WYSIWYG. Would only advise having one tab on ebid site open until you accomplish it as it can be confusing... Oh & don't forget to save each change
To recap HannaHolly's instructions:
Go to your "My eBid" Go to "My Defaults.
Check plain html box then click Save General default
Go then to your "About me" page or edit auction which will automatically show text as html.
Copy & Paste the extra scroller html to your about me page or auction at the bottom of your existing html & Save the page
Then go back to my default page & change back to WYSIWYG. Click Save general default
Refresh your browser if necessary.
