Just discovered this too, is this being looked at? It does make post-match analysis much more awkward.
Computer Analysis
Hey guys I'm having this problem too. Jac1yn will you keep us updated with this issue please. I will now track this topic. Many thanks
Hey Boldie, just tried it & yes mine also works when using arrows. Cheers, that will do for me until teh glitch is resolved properly......
MCCloak figured out if you use the arrows on your keyboard instead of clicking on the arrows, the board doesn't reset :)
That works! 
The only thing I've been able to figure out is that if you use the page's buttons, it tries to move forward the entire move rather than just black or white's move. Maybe the board is linked with the keyboard and doesn't use the same function as the buttons do? (though I can't see why they would use a different function
). Either that or it's somehow registering a double click.
Then thanks to MCCloak :) ... atleast we can still use this facility until it is resolved properly........
Whenever I use the Computer Analyzer tool and start clicking the > button the game will move 1 move forward then go back to the beginning of the game, I thought this was just me but there are 3 of us that live here and its happening to all 3 of us? Is this a known problem or is this somehow just our computers. 2 of us use google chrome and 1 of us user ie8.
