My Update Panel is inside a Tab Panel and the effect I am going for is to show the update progress panel by fading out the rest of the page.so when you click the button its like a modal popup that displays the spinner on updating and then on updated it fades the page back, but I think the process is interrupted by a panel postback and then nothing fades back in.
