When I click on a file to zoom to 100% it zooms to 800%. I had the same problem in CS5 and fixed it by deleting the com.adobe.bridge.plist, but this does not work with CS6 and I don't even find the plist. I have a Mac with OS X 10.8.2. I found two plists, com.adobe.CSXS.3 and com.adobe.CSXS2Preferences but it didn't fix the problem deleting them.
I use the zoom function alot and would be very grateful if someone could help me. I do not like the preview workspace with the little 100% window, I prefer zooming to 100% by clicking on the file.
