This problem is happening on Puerto Rico and is making it hard to use the interface. Here's how it gets in the way.
There are actually several interface changes that I noticed when poking around.
1. If you move your mouse arrow to the bottom of the list of roles and move up through the list, the tool tip/popup explaining the Captain role appears. As the mouse arrow moves up the list onto the popup the popup does not go away and you have to move to another area of the screen to force the game to popup another tool tip on another part of the screen. Then you have to carefully go back and move your mouse from the side onto the Role you want to choose. If you're not exact enough, another popup gets in the way and you have to repeat the process.
2. At the end of a game the "Discuss at this Table" dialog can't be used anymore. Apologies for any apparent rude behavior at the end of a game.
3. When clicking my statistics for a game, the graph has changed into a single red line graph.
