Key-in to accept a prompt to save HELP!

Hi,

We're trying to write a script for Bentley Navigator to open DWG files and automatically export into COLLADA form. Everything works well untill we script to exit the file and open a new one. We can't figure out how to get past the "Would you like to save before quitting, yes, no cancel" user prompt.

Any ideas?

The script is launched from a batch file. This what we have so far:

@echo off
:begin

START "" "C:\Program Files (x86)\Bentley\Navigator V8i\Navigator\Navigator.exe" "file name" -sC:\Users\user name\Desktop\ExportCOLLADA.dscript

And our script:

EXPORT COLLADA C:\Users\user naem\Desktop\
