Thanks for the discussion. I had tested my script and it worked for me. I agree that just 5 parameters may be not enough. But there is no need to put the sleep command in. I had the impression that the script waited until the cygstart command was finished. But even if not -- Notepad loads the file completely into memory and then releases the file handle, so one can delete the file while notepad is still open.
