when calls execute?

[anarchist]

I've been wondering about how some of my javascript works

I have a function that when called, closes the current window or changes page, then opens a new one using values take from the old

logically once the page has been changed or closed the values are no longer available, come to think of it the function should have gone too

I guess what I'm aslking is, when a function is called that contains window commands are these commands qued for execution after the javascript?

I also have functions that alter page content and am wondering how I'd get javascript to display the changes when they happen?

I know when I used VB there was a call to allow windows to do its stuff and update the diplay
if theres something similar if could be usefull as I have some big functions that take a while to run and it would be nice not to completely lock up the brower while they run
