Skeleton code ..

I appologize if i do something wrong 
but looks to me strange that randomizeTimer()
close window ?
Is this some sort of quirk or bug ?

sys : win7_32bit

look into example 


'skeleton code for rc_basic
xmax = 640
ymax = 480
w=0
title$ = ""
center_x = windowpos_centered
center_y = windowpos_centered
WindowOpen(w,title$,center_x,center_y,xmax,ymax,WindowMode(1,0,0,0,0),1)
SetWindowAutoClose(1, 0) ' <<<<<<<<<=========== 1,0 window#1 0,0 window#0
CanvasOpen(1,xmax,ymax,0,0,xmax,ymax,0)
ClearCanvas

'randomize(timer)  ' uncomment this line close window ?



while WindowExists(w) > 0   ' (1) window#1 (0) window#0
'While Not Key(K_ESCAPE)
update()
wend

end
