Hi Marc, Thanks for your help.

Now the app works better, since I can close the 
this.g_objfrmChild by doing this.ActiveMdiChild.Close(). But 
how come closing the Child does not automatcally set it to 
null. So even though the Child is closed, next time I click 
NewChild menu item no Child is displayed. Any suggestions?

Regards,
Peter
