User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:2.0b12pre) Gecko/20110218 Firefox/4.0b12pre Build Identifier: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:2.0b12pre) Gecko/20110218 Firefox/4.0b12pre When the tabs were not in the title bar, the Panorama button was placed such that whether Panorama was active or inactive, the button would be in the same place--that is, I could activate and close Panorama with two clicks without moving my mouse. This is no longer true. I can move the Panorama button to next to the search bar when it is inactive, but it still does not have complete alignment with the Panorama button when Panorama is activated. When a user moves the Panorama button in the Panorama inactive interface (through right click-->Customize), the button should also move to that spot when Panorama is active. Reproducible: Always Steps to Reproduce: 1. Activate Panorama with Panorama button. Actual Results: Panorama button moves to the right when Panorama is activated. Expected Results: Panorama button should remain at the same spot, whether Panorama is active or not.
