Actually, upon re-reading the above, it looks like it's a bash quoting
issue. You might try the fix that worked for "cygstart": single quote the
double quotes, e.g.
or, if you want to be more generic,
tlib '"'"`cygpath -w "$FILENAME"`"'"'
Make sure you copy the above *exactly* (better yet, cut/paste).
Hope this helps,
