My guess is that in the FILE/FILE OPTIONS you have perform OnOpen on startup.
This is my first guess too, second guess is maybe the layout has a script trigger set up on it.
There are actually 2 options available.
In the File >> File Options Menu you can decide if you want to go to a specific layout when the file opens or you can script this and have the database perform the script when opening. The method really depends if you are going to have multiple layouts for different privledge sets.
Thank you all. Thank you Peter. The File Options>>Perform script indicates the missing script. It works well now.
