ACR 7.3 on a Mac

I searched Adobe bridge forums and Mac Talk to see if anybody else has encountered this. Any help or ideas would be appreciated.

I've got three symptoms of a problem with Adobe Bridge CS6 after loading the update for ACR7.3.

1. I can't open up Adobe Raw Preferences in Bridge. It is not grayed out. It just doesn't do anything.

2. The raw images form my new camera (Panasonic GH3 extension .RW2) show as blank piece of paper.

3. When I double click on the RAW image in Adobe Bridge CS6, it opens ACR 7.3 with the photo. But it has opened ACR 7.3 in Photoshop and not Adobe Bridge.

So I can process the new .RW2 images. I just can't see what RAW image I have selected to work with in Adobe Bridge CS6.

I running OS X 10.6.8 in 64 bit mode.

I have a number of older versions of PhotoShop that I've never un-installed (CS4 & CS5)

It would be nice if I can get Adobe Bridge CS6 to show my .RW2 images. Anybody else hear of some else encountering this problem.  Thanks in advance.
