page refreshes in html...make it so people cant do anything?

Hey. I was just wondering if this was possible.

I have a page which currently has a bunch of Ajax, and at the end of some of the ajax i force a page refresh (window.location.reload(true);) ... And I would like it so that no one can click or anything while the page is reloading (it really messes stuff up)...

I was wondering if there was a way to make it so that people cant do anything? like while the page is reloading have a full screen popup that says "loading" or something?

sound do-able?

thanks!
