We have macs and windows computers here. The Mac users will write
filenames with wacky characters. My PC will see them fine (I am admin
equivalent), but the same Mac users will log in to a PC and not see the
files. Change the file name an bingo they can see the files when logged
in to a PC.

Ok, so I fix the folder / file names. But why could I see them? It seems
as though user rights are involved when they shouldn't be.

Any ideas?
