I'm using Path Finder and have it set as my default file browser. When I use Alfred's "Open file..." function to access a file folder, that folder is revealed in the Apple Finder. (This shouldn't be happening since I have Path Finder set as my default file browser). However, when I use Alfred's "Reveal file in Finder..." function to access that same folder, the folder is revealed in Path Finder. (This is what should be happening since I have Path Finder set as my default file browser.)
I'm using Alfred v2.0.2 (178) and can replicate this issue. I have a new MacBook, 2.5 GHz Intel Core i5, 4 GB 1600 MHz DDR3, running OS X 10.8.3
