Problem in chromeless window

[munnan]

Hi gulls & guys,
I 'm facing a problem when I try to open a chromeless window in flash i.e.

http://www.kirupa.com/developer/flash5/borderless.asp

I'm unable to position the window on the screen as 0 x 0 (on top left corner) ,
so if any body knows how to do it , tell me :)
thnx,
bye,
maani
