Hi Kevin,

I get a compile error on the line

this.MdiParent = App.MainForm;

Error message is :

The type or namespace name 'App' could not be found (are you missing a using directive or an assembly reference?)

The form, which the code is put on, is a mmBusinessForm which also uses (using) MM.Main.Windows.Forms.
References of interest in the project that the form is placed in is :
Mere Mortals Framework
Mere Mortals Framework Automation
Mere Mortals Framework Interfaces
and Mere Mortals Framework Windows Forms.
