I recently upgraded to CS6 and the functionality of mini bridge has changed dramatically. Here's my issues:
Multiple folders of images along with subfolders:
When you click on that main folder, none of the subfolders are shown within the browser window.
Keyboard commands do not follow proper folder path actions like it used to:
When you used the Command Up Arrow or Down Arrow, you could drill into and out of folder directories. When you use this command, it does not show the next level up. Only the tiny path up on the top. So NO subfolders get shown within the browser window. It's that second window in the navigation in CS5 that was removed. Why??
