Thank you, BobS! After some investigation I do the following, but not sure I'm doing right.... 1. Added a shortcut to start_servers.bat to startup folder. 2. Commented out the pause call in start_servers.bat. 3. Run start_servers.php with parameter 3 in batch file and then call portable chrome directly from start_servers.bat along with http://localhost/ parameter. 4. Step 3 fixed that. Is there something I do incorrect way?
