Outdated / Resolved: "Analyze" board stopped working properly

Today (5/1/2011) a bug started happening with my analysis boards.  When I play out a line, then back it up, it won't let me pick different moves.  Happens under Firefox 3.6.16 and also with Google Chrome.  This is a new problem, and has never happened to me before.

Yall change something in your back end?

Never heard of that myself

Analysis board is not working with my Windows Vista/Chrome.

Are you able to post screenshots of what you're seeing?

Thanks for your reply.

This image is Position Setup option, after clicking on InitialPosition (not working well).

Are you able to see pieces and boards elsewhere on the site?

The "Daily Puzzle" and Tactics Trainer work ok.

Are you able to see it now ?

I'm not sure if I do understand.  I am able to see (and play) "Daily Puzzle".  But the Analysis Board is not working.

Analysis Board now working, with the new layout, which is great (except for too much white).
