Anybody else experiencing this issue?, it started saturday morning

I was getting an error message this morning, but it worked tonight. I don't know how long that will last.

 it's working! :-)) thanks.

I get an error msg "[load: class com.chess.applet.ChessApplet not found]" while playing chess against Facebook computer. I tried I.E. 8, Firefox, Google Chrome and get the same results. No gui for chessboard.

show pgn text can't be copied from within the java applet window

using firefox 3.6.xxx, updated java, all noscript permissions,

show pgn dows show the pgn, text is selectable but control^c or right-click does not allow copy that will paste in a windows vista new text document.

i can only do a printscreen of the applet windows, and that becomes cumbersome with longer games. 

is this known?

thanks
