Hi Yermah,
That is quite strange. I just posted a test listing using eBay's new SYI form, containing only the stre window HTML in the description, and the store window was correctly displayed on the auction once posted. This test auction can be seen at: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=130073254787
If you would like further assistance with this matter, please file a support request using the appropriate link on our help page:
