Hi I am using Ajax control toolkit modalpopupextender and I use it to popup
a form that allows me to select certain controls and submit using a button.
Problem I have is that whenever the page refreshes due to submit or any
similar behaviour I see the form quickly popup and disappear in the
foreground.  Now this is not a critical issue, however it is very apparent
and I would like to know if there is a solution to this problem or if anyone
has any advice on how to integrate a popup form without this issue.

I appreciate any feedback.
