... In the plain text case, I would recommend TextWrangler (BBEdit's free cousin) as it can set the line ending style for Windows.
So for plain text, if I get TextWrangler and set the line ending style for Windows (CR LF or something), will this plain text file still read properly when double-clicked on a non-Windows (e.g. classic Mac, OS X, Linux) system?
Thanks for all the help.
