Yahoo just updated their fantasy football interfaces.
It looks nice but does not scroll at all when using the kindle fire.
I reported an issue to yahoo regarding this and was informed that they were investigating. Haven't heard anything since.
I can no longer use the Fire for this. I would usually have it by my side to monitor stats during Sunday afternoon games.
Grrrr.
UPDATE: Hold the Fire in portrait mode and most of the pages will display. This makes things usable for the most part.
