Hi all,

I open a borderless popup window from a .aspx page. After updating data in the popup window, i close that window. When i navigate in my parent browser window, few of my session variables are set to nothing. I am sure that this occurs because of the popup window. When i open the window using window.open, my parent window maintains the state.

I need replies regarding opening a borderless window and maintaining the state. I took the chromeless.js from this site only.

Thanks and Regards,  
Mani.
