If you are getting a "page not found" error, I had this problem. The answer from ebay is annoying, but works. The problem occurs with problems with cookies, and I think java. The solution is to always start from the ebay home page, then go to "my ebay" or the category you want. Then, search will work This fixed the problem for me, sort of. If I continue to navigate through other categories, the problem does re-appear at times. Then I have to close all the ebay windows and start over at the ebay home page. The ebay rep acknowledged this was an annoying problem reported by several members.
