I do have the Classic style selected. It loads the fastest and gives the best color contrast ratio for my vision/perception.

It was working before, but no longer does.

The only change to my system was the addition of two 8 GB SDHC cards. I haven't even installed any new software yet.

Thus the reason for suspecting that some change was made to the website so that the browser doesn't detect the search text box as needing data entry.
