AJAX Animation and timeouts

[Teldin]

I have a long running aspx user control that has javascript function to display a message when the timeout has occured. I have a AnimationTarget to disable the "Submit" button (which causes the timeout if the database is busy) but when the timeout occurs, the page has to be refreshed for the button to be enabled again. Is there a way I can re-enable the button (via the javascript maybe?) without refreshing the page?

Thanks
