ASP.NET used in PocketPC IE / Large data problem

[Vector7]

I am using ASP.NET application in a PocketPc IE Webbrowser. The main page redirects to a new one, which creates a list of large data ( for example 100 entries ). At the bottom you can find a "Back" Button. As long as the list is short, the List page redirects to its main page fast. But if it's long then the browser is "thinking" and finally give me an error message "Site cannot be found". Don't know what the problem is.
