2 Update Progress !!

Hi

I have a website that uses many updatepanels

each one has its own Update Progress spinner

the problem is that when i click on UpdatePanel 1 button the spinner work fine

while the spinner still spinning, If i click on UpdatePanel 2 button the spinner of (1) stops althoough the process not finished yet and the spinner of (2) begins

you can look at http://problex.com to see it live

Thanks
