I have to use location.hash = whatever because the window that opens doesn't have it's own web address. Is it possible to give it one? With
// In one of these two?
FactorsWindow = window.open("", "", "location = no, menubar = no, personal = no, scrollbars = yes, status = no, toolbar = no, resizable = no, width = 580%, height = 600%, left = 720%, top = 100%")
If it is please say how
