window.history.go(-xx) question in ASP.NET

Question

I am having a problem with the window.history.go(-x) function in my javascript.  I am arriving at a new page using Response.Write(x.aspx).  From the x.aspx page, I want to go back to my parent page, but, the code doesn't go back.  The window just flickers and stays on x.aspx page.
Is there something that I'm not doing to enable this function?  All I'm trying to do is go from my parent page to the child page and back (without losing controls/information) on my parent page.
Thx,
KD
