[cvsnt] Blank lines and strange characters in text files

[Jeff Harmon]

We have a problem where there are some text files that end up with blank
lines (every other line) and strange block looking characters.  The
files were committed using cygwin instead of cvsnt, but they are DOS
formatted files.  When I open the file that was checked out using cvsnt
in cygwin the files show ^M characters at the end of every line.  If I
check the file out using cygwin cvs, the file is fine in any editor I
use.  
 
Does anyone have any experience with something like this?  Is there a
cvsnt option I can use to make this problem go away?
