I was doing a search today, and got a message something like "will not be complete until indexing is finished". I had to option to have it start indexing, which I did, took 23 minutes.
It's not a big issue, I just thought that the updates indexed automatically unless I told it to stop. Is this suppose to be automatic? L4.0b beta 5(4.02.3.5543) on w7/64.
