I'm trying to open a file via any app (e.g. Photoshop, Handbrake) and when I click File -> Open and try to list out the files on my LOCAL drive, nothing gets displayed in the dialog box and the spinning icon on the bottom left keeps spinning with nothing displayed. Does anyone else have this problem? I've added a screenshot to let you know what I mean. I have a Retina MBP with OSX Mountain Lion.
