Several times this has happened. I am viewing files or videos in Bridge and the window shrinks back to the icon on the taskbar. If I hover over that, I see a preview of the folder and contents of what I was just on, but it won't open. In another case, just the filename showed and that desktop turned from blue with icons to gray and blank. In one case, I rebooted as all the other icons shrank and became response and I had to reboot. Last time I used task manager to restart Bridge.
