It works fine with Safari 8.0.3 so it might be Firefox related. Have you tried with some other browser as well, like Chrome?
Games Editor Problem

Yes I've just tried it with IE and I have the same issue. It's also the same on both my laptop using Windows 7, and my old PC running XP.

Oh, you're right! I was still in the Analysis board tab. It works there, but as you say, it doesn't work in the Game Editor tab. Definitely a bug/oversight then. Well, as long as one doesn't need any promotion a variation, I guess one is fine...

Oh glad it is not just me. Yes this is an annoying bug, I have sent a ticket. I could use other editor pads, but I quite like this one and I have just paid for my subscription again and such things should work.
Hi, the Games Editor on here - More/Game Editor - doesn't allow me to promote a pawn when entering game details. I'm using Firefox. Any help appreciated, thanks.
