I've already sent a direct message to Dan but I've not heard back yet so I thought I'd post here to see if it is happening to anyone else.
For the last few days almost every time I click on something I get the blue "thinking" bar and the action doesn't happen or it does very very slowly. It's making playing the game almost impossible and I almost blew my upkeep because I couldn't sell minerals.

Is this happening to anyone else?
Before anyone asks I've cleared my cache multiple times and have restarted my machine & browser twice. I'm running the current version of Chrome on a Mac Mini with OS X Snow Leopard.
