I would imagine they support all major browsers, but I would lean towards Chrome if I were you. Do you have some sort of setup that auto refreshes the page every minute or couple minutes or something? That might get in front of the issue your having if you don't.
Edit: Also I understand your frustration. The old map view system all around worked great, and the new view modes have been so buggy I'm not sure how they are passing QA before they get pushed to us customers.
