Photoshop needs a Scripting Addition called "Adobe Unit Types". It's located in "/Library/Scripting Additions". If you have your old top-level Library, just drag it back into place. If you don't, you may need to reinstall Photoshop.
This actually isn't a Tiger thing. The same was true under Panther (it hit me after I did reinstalled my system once). It's just that Photoshop does something really bizarre.
I owe you one too! I noticed my jaguar computer didn't have the Action Scripts for Adobe but my Panther computer at my contract work site did. I just copied it, took it home, and now for the first time in 2 years I can open photoshop files by double-clicking them!
Ya Mikura..I just did a reinstall, and have that problem. I copied the "Adobe Unit Types" from Previous Systems and still not working. Looks like I need reinstall PS. I can't seem to be able to install my wacom tablet driver either. The install keeps freezing up. Any solutions there? Thanx.
