I added a new main window, w_main_tab to our applicaton
users can select the current style or the tab Window style

The clicked! event of m_main.m...  has 1 line of code depending on the Window type (floating, sheet with parm, sheet)
of_window_open_sheet( ref w_windowX ) 

this is the programming on m_main.of_window_open_sheet (the programming is similar for the w other types of Windows)

    string    ls_errorString 
    SetPointer( HourGlass! )
    
    of_setmicrohelp( 'Working...' )
    
    if isValid( w_main )=True then 
        OpenSheet( aw_window, w_main, 0, original! )
    else
        OpenSheet( aw_window, w_main_tab, 0, original! )
    end if
    
    of_setmicrohelp( 'Ready' )
    
    Return

All 3 of the menu functions work as expected

When i put the exact same programming application functions, the Window value is NULL and fails to open

No matter how I've declared the function, the value of the Window object is null in both cases
application.of_window_open_sheet( ref aw_window )
application.of_window_open_sheet( aw_window )

thanks for any help
