Why are you using a HTML button?
Just run it from command line and the MD-DOS window won't disapper.
So you can see the result.
If you don't want to see the dialog box anymore,
when the dialog box comes up,
select 'Open this file from it's current location.',
and then uncheck the box that says:
'Always ask before opening this type of file.'
then hit ok and the dialog-box won't come up anymore.
