TL may be a good work around for some, but the point is that the lister in ebay should work properly, not need a work around.  It is the life blood of the site after all.

Ebay is slow at the best of times - and I have really good ADSL2+ connectivity, often 1mbps download rate - why should I have to perform extra page refreshes and mouse clicks to perform the simplest, most basic task on ebay?

My only solution for this problem has been to relist something that doesn't have best offer already, making sure I edit the listing in some way.
