Hi,
I used shutdown in form_unload and never got such problem
Private Sub Form_Unload(Cancel As Integer)
IaxClientOcx1.Shutdown
End Sub
It might be some timer or your VB function which is using the control (or any control\'s function or property) after it is terminated and shutdown.
I removed the license screen from init() and place it in system tray, thats why system tray is implemented, I think it is not removed properly when it is terminated, i am working on it, and hope i can fix it.
Thanks and Regards,
Babar Shafiq Nazmi.
