LB5 Testing 350 window_nf Error

[Mark Dunham]

So I have been testing LB5 350 and when I create this simple window_nf I keep getting this error Message not understood: #topComponent. When running the sample programs include with the alpha I do not get this error also if I remove _nf I do not get the error. What am I missing? Or is this a bug.

nomainwin
WindowWidth = 800
WindowHeight = 600
UpperLeftX = 10'int((DisplayWidth - WindowWidth)/2)
UpperLeftY = 10'int((DisplayHeight - WindowHeight)/2)

open "New Window" for window_nf as #main
   #main "trapclose [Quit]"

wait

[Quit]
   close #main
   end

I suspect that window_nf type has not been implemented yet. Type window_popup is also not implemented.
