Windows have restrictions on filenames. The restrictions are not 
consistent in that some parts of Windows will let you make names that 
other parts do not recognize or regard as illegal. I ran into this some 
years ago and there may be a discussion on the tracker, but I have 
forgetten the details except that one of the 'parts' was Windows 
Explorer. This *might* be what you are running into.
