The problem is with the way 'nix and DOS/Windoze handle EOL in txt files. DOS/Windoze represents end of line as a Carriage Return + Line Feed combination (x0D0A)
'nix on the other hand uses just a LF cahracter (x0A)
[and just for the record - Mac uses just a CR (x0D)]
This was what caused the problem - Linux couldn't succesfully read the DOS text file because of the difference in formatting.
There are (freeware) programs which enable you to read/write 'nix text formatted files under windoze (as well as improving drastically on Notepads limited capabilities). Let me know if you'd like more info.

The only things that give you the problem are scripts (text) files created on one system for use on the other, as noted above. A straight binary copy of a file shouldn't be a problem.
