New use to Bridge. Opened Bridge CS4 (in Mac OS X) and selected a photo in the Essentials work flow. Clicking on View - Full screen Preview on the menu bar doesn't show the picture full screen. Observation is, When I select it, the entire Adobe Bridge CS4 menu bar disappears. Only after closing the Bridge window do I see the main application menu bar. Then had to open a New window from File menu to get back to the essentials work space. But it was working before. I tried the spacebar too, but doesn't work. Don't know what settings are changed. Some one help in seeing the full screen preview.
