Thanks.

I have been using it in many of my projects for a long time.

I have sent _GUICtrlMenu_InsertMenu() UDF proposition to standard inlude files unfortunately it wasn't accepted.

There is already a function to do that: _GUICtrlMenu_InsertMenuItem (but less options)

I know about that.

I have just created _GUICtrlMenu_InsertMenu() on the same basis as existing _GUICtrlMenu_AppendMenu()
