Every time I attempt to use the Photomerge and Merge to HDR features in PS CS3, it crashes on me when I click the "Browse" button to select files. I've tried deleting preferences, caches, etc... to no avail. Any ideas as to what may be causing this? I want to try and figure this out before I try reinstalling. I'm running Photoshop 10.0.1 and Mac OS 10.5.4.
