Popup window without focus

[zxmn50]

How can i create a pop window without focus on it.

I have a situation where user may be working on some other applications, and my application browser refreshes and makes ajax calls to server for status, on a particular status, i want to popup a browser window, but users should be able to continue what they are doing without disturbing.

After the window does whatever it might do that is bringing it to the top, have it do a:

self.blur()

That will send it back below whatever was on top before, usually without appearing on top at all.

well, i don't even want to focus on parent window. Parent page could be refresshing a javascript function, that function would be claling server code on some status.

User might be working on some other windows, Without user events and getting focus on parent window, i want to open a popup window.
Lets say user browsed parent window, and now typing a mail from outlook, and that browser window finds some status on server, and it needs to open a popup. User shouldnot panick, and continue what he is doing on outlook without losing focus.
