Hi Marc,
I am not sure that you are using the unique ID of the form.
Can you run this to make sure,what forms are open :
String FormUIDs = ""; for (int i = 0; i < SBO_Application.Forms.Count; i++) { FormUIDs += SBO_Application.Forms.Item(i).TypeEx+":"+SBO_Application.Forms.Item(i).UniqueID + ","; }
regards,
Maik
