[Leica] Strange Photoshop CS / CS2 compatibility issue

[lug at steveunsworth.co.uk (Steve Unsworth)]

Hi Nathan

Under the file handling preferences there's an option 'Maximize PSD and
PSB File Compatibility', make sure you've selected 'Always'. There must have
been some changes to the native PSD format for CS2 which presumably why they
added the option.
