Have just sent this enquiry to Technical Support - I think the message is self-explanatory:
"I am experiencing frequent glitches on the website when I am trying to compose new listings or edit existing listings.
The problem appears to concern the 3rd party banner advertisement at the top of the page. This banner does not load, and in doing so prevents certain other functions on the page, especially with regards to the Auction Description box which gets stuck in HTML mode.
The relevant URLs of the banner appear to be: http://cache.adviva.net/creative/blank.gif ... and http://ad.yieldmanager.com/frame ... These sources appear to use javascript and html.
I don't know why this should happen but until that banner loads succesfully, I find I cannot use the WYSIWYG editor to write or amend listings.
Any advice on this please?"
Anyone finding the same problem?
I've received the Support ticket and await their reply (shouldn't be too long). Note: the above urls are not complete.
