[galzv]

hi

can somebody please help a dummy newcomer how to find out what actually 
works on osx using Windows.Forms. i now have a working example with 
buttons, and textboxes, but as soon as i try adding a menu, the app 
crashes

// some source:

	MenuItem mnuOpen, mnuClose, mnuExit ;
	MainMenu mnuMain ;
	MenuItem mnuFile, mnuWindow ;


    public Galzvizm()
    {
    
    	mnuFile = new MenuItem() ;
    	mnuFile.Text = "&File" ;
    	mnuFile.MergeOrder = 0 ;
    	
    	mnuWindow = new MenuItem() ;
    	mnuWindow.MergeOrder = 2 ;
    	mnuWindow.Text = "&Window" ;
    	
    	mnuMain = new MainMenu() ;
    	mnuMain.MenuItems.AddRange( new MenuItem[2] { mnuFile, mnuWindow}) 
;

	// up to here everything works but as soon as i uncoment the following 
line, the crash occurs
    	this.Menu = mnuMain ;


i'm more looking for the way to go on finding out what works (do i have 
to skim through the svn source, or is there a list that is regularly 
updated and specifys implemented functionality) than help with the 
above snippet.

thank you guys
