Yeah, this seems to be sporadic but everything was working for me today. Try backing up (use browser back button or select an earlier SYI page) and go forward again - that sometimes works.
Today's problem for me is the 'tiny font' fiasco - again - necessitating the removal of all paragraph HTML code from my auction descriptions to get around it.
I mentioned in a post on this board a while ago that I thought that eBay did a remarkably good job technically, given the size and scope of the website.
I'd like to go on record as formally retracting that statement.
