This problem is systemic. I sent a trouble report to the site Admins. You may also notice that there are no navigation buttons in the Analysis window, and that the Diagram Editor will not let you change the size or location of your board when trying to insert it into a post.
Also, I rebooted all three of my systems (Windows, Linux, & Mac), and the problems still persisted. I also tried all four of the browsers I have/use; IE8, FireFox, Chrome, & Safari. Same issues with all of them.
This mornig I wanted to join a Votechess game of my team.
Normally there is a yellow box in the upper right corner where you can choose your team.
But since the newest Site-Update there is only a little yellow field and no way to choose the team and to join the game.
Ctrl + F5 doesnt help. Someone else with this problem or with a solution?
Here a picture with the blank field instead of choose your team:
