I have a recommendation for fixing the freeze problem. In Chrome when you are on BBO, in the address bar to the left of the www.bridgebase.com you can see either a lock or an i with a circle around it. Click on this. Change as many settings as you can to "allow". It's okay because it only affects the BBO website. You don't want to do this with websites you're unsure you can trust. After you change your settings, be careful not to change them back to default on the way out, you should be good to go.
