Page scrolling problem

[Mukesh]

I'm struck in strange problem. In one of my forms I use RadAjaxManager, RadAjaxLoadingPanel, RadTabStrip, RadMultiPage and RadGrid along with some other controls. The page works correctly. My problem is that, when I scroll down the page, it will go up automatically. When I scroll up, it will go down. What would be the problem here?

One more problem is there, the loading panel is not working all the times. Its showing the loading image only some times.
