Search still not working and Other small bug

1.) Whenever I type in search, it asks me to "Please type in search key" every time?
2.) In Mozilla when I goto the front page of vshare (logged in) my ID disappears and the log in link appears again, but only on the home page of vshare. When I click the upload button my name will reappear. This does not happen in Internet Explorer.

Unbelievably thats It!! Wonderful job you guys have done on this project and would like to thank all involved in the development.
