Subject: [Leica] Strange Photoshop CS / CS2 compatibility issue

I had a weird issue the other day, which I hope some of the Photoshop 
experts here can explain.

I use PS CS on my desktop PC at home (Windows XP). Until recently I also 
used PS CS on my Powerbook, and was always able to move PSD files 
seamlessly between the two computers. But recently I upgraded my Apple 
Photoshop to CS2. This is what I used to process all the images I made 
during the trip to Poland. When I came home, I transferred the files 
from the Powerbook to the desktop. And here comes the strange part: some 
of the PSD files I saved in PS CS2 on the Apple will not open in PS CS 
on the PC. Now, if this were the case with ALL of them, then I would 
simply conclude that the PSD files simply are not backward compatible. 
But it seems completely random; only about 10-20% of the images are 
affected, and there is no systematic difference between the images that 
will open on the PC and those that will not. The problem affects only 
PSD files; TIFF files that I created in PS CS2 open in PS CS with no 
problem, 100% of the time.

Does anyone have an idea why this might be happening? Is it a 
compatibility issue between OSX and Windows, between CS and CS2, or a 
combination of the two?

TIA,
Nathan
