If you use Photoshop CS and have recently upgraded to Tiger via Archive and Install, you may have noticed that you can’t drag and drop files or double-click on them from the Finder to open them. The only way to open the files is via the File Browser or the Open dialog box. Needless to say, this is very annoying.
The problem is linked to the Archive and Install feature of the Mac OS X installation process. To restore the functionality, you’ll need to reinstall Photoshop CS. I don’t know if this problem is duplicated with Photoshop CS2.
I looked everywhere for a solution to this problem before finding the answer on Macintouch’s Tiger Reports pages. I didn’t enter the right Google search terms to find this answer apparently. “Tiger Photoshop CS Drag and Drop” brings up the listing quickly but not “Photoshop Drag and Drop Problem Open Mac OS X”.
