Hello Sergey
Thank you for your answer.
All my forms are modal.
Is this a problem only for my testprogramm ???

Normaly i would like to have a main programm for my application.
enviroment...
connection to get a public connection number
logonscreen (modal)
menu (with modal forms)
disconnect
quit

If this will not work, is there a workaround ????
Normaly i would not prefer to start or end a connection at the init or unload event of each form.

Best regards
Albert
