Page visibility using javascript

[viswa_007]

Hi,
I am facing a problem with alert message on my web page.
When alert message is shown, my current web page which fires events automatically
after 3 seconds stops until the alert message is gone.So instead i want to use a div which
if shown as alert msg my current page has to get disabled for user but the events must get fired as it used to ...(for example in microsoft's website when silverlight install option comes the page gets disabled)
So plz help me with some ideas.I am developing an asp.net web solution using c#.
I need a javascript code or suggestions for my problem...

Well this post here describes how to use modal divs, switching visibility of elements is all over the site so use the search box up in the right corner there.

You will have trouble with IE, because it won't update the screen until the script stops running, or an alert appears.
