Aha. Thanks for the verification. I had a separate location bar when I did this. I just tried again, and it still didn't work. But then, without quitting, I turned off the separate location bar, went into the toolbar customization dialog, where the location bar no longer appeared, and added it back -- a known problem with removing the separate location bar. The search field was still unaffected. I removed it, put it back, and got the desired results.
