Want to display a "Busy: Please Wait" modal dialogue while pages postback

I have a number of forms where some of the inputs can cause a postback.  I've run into issues where the user will change one of these autopostback inputs, tab to the next item, and start typing only to find it gets wiped out a couple seconds later once the page postback is complete.

To address this issue, I'd like a little "Busy: Please Wait" modal dialogue to appear while the page is refreshing - maybe in the bottom-right so it's not so annoying.  While the dialogue is up, it should prevent the user from typing in the main window (in other words, it would need to behave like a modal dialogue).

How would I do this?  If client-side scripting is required (I'm assuming it will be), I'd prefer to do this with JavaScript

why not do a "one click button" instead of an annoying pop-up?
We use this, and it works great...

This is close to what I need to do, but not quite.  I need a modal dialogue as described above.  This is so that the user can see the form while it refreshes.  Any ideas?

bthews -- how did you implement this?

Can this be done as an overlay on the original page?
