It's impossible to log into eBay on Tear. I get a Save Dialog Box instead. (You can put anything in the User ID and Password text boxes to recreate the problem -- you don't have to enter a valid ID or Password.)

(This may be the already frequently mentioned "bookmarklet" problem. Reading about "bookmarklets," I wasn't sure if a log-in button was a bookmarklet. It's similar to problems I've encountered when trying to preview a Reply in "Advanced" when posting on this forum.)
