Popup in Safari OSX opens different size than Safari on Windows -

-

i have code

window.open(null, "window", "status = 0, height = " + wizard_height - 50 + ", width = " + wizard_width - 50 + ", resizable = 0");

for reason in windows safari opens ok, in mac (osx) opens in full screen!

how can be?

thank you

instead of 

"status = 0, height = " + wizard_height - 50 + ", width = " + wizard_width - 50

use

"status = 0, height = " + (wizard_height - 50) + ", width = " + (wizard_width - 50)

apparently javascript engine of latest safari on os x thinks 

"status = 0, height = " + wizard_height - 50

as 

("status = 0, height = " + wizard_height) - 50

and makes "nan", can see evaluating string in safari's debug console.

by way, know safari has debug console, right? go preferences, choose detail tab, , check "show developer menu" toolbox. can open web inspector, javascript console, etc.
