Cant castle
Here is a link

And it's standard chess in my recent games I had to manually castle.

I see what you've done. When you highlight your king, click next to your rook, instead of one square towards it.
I am having a problem with castling in game, this has caused me to lose a lot. The positions I am trying to castle in are legal, and I have tried switching between different browsers firefox, and google chrome.
