<p>This line:<br>
%f "\r" && exit<br>
has the same effect as:<br>
D:\Comodo\Dragon\dragon.exe %d\%f && exit<br>
except it now uses the default browser instead of dragon.<br>
"\r" is a DOS carriage return; i.e. "Enter" or "Open" or "Execute"<br>
The problem with the opening and closing of a DOS window persists.<br>
Perhaps what is needed is the equivalent of the HTML setting </p>
