A weird problem is happening every 1/500 times page is used. When page
posts back, it briefly shows ViewState in the browser just like it appears
when you do "view source", then shows the original contents of the page
before button on the page has been clicked.

This happens on Windows XP Professional with service pack 2 and IE 6.

<input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE"
value="/wEPDwUJNjY0NjM0ODIyD2QWAmYPZBYEAgMPZBY....


Page is a simple Web Form that has simple Master Page. Web Form contains
MultiView control, inside MultiView control is a View control that contains
a panel with dynamically added Web Controls and button user clicks (as
described above)

Any help would be great!

Thanks!
