This is driving me mad. So much so that I have installed and started using Chrome, but there must be an answer.
When I start typing in the Google search field, the autocomplete text comes as usual, but clicking on the line of my choice does nothing. Same for selecting and hitting return. I have to type the whole thing out. It worked fine in in Beta 9, but 9.0.8080.16413 nada.
What is really frustrating is that it is total reflex to click on the autocomplete text, so I forget it is not working and try to use it EVERY TIME!
