In OOTP 9 the HTML output by the Almanac included a set of dropdowns on the scoreboard that allowed you to navigate throughout the season. The same dropdowns are present in the HTML output by the Almanac in OOTP 10, but they don't seem to work for navigating.
Compare:

to see this in action (or inaction, as the case may be).
I've confirmed this on Safari, Firefox and Camino on a Mac running OS X 10.4.11.
Obviously this isn't terribly critical, but I figured it should be noted somewhere.
