I'm fairly new to ASP.NET, although I have a fair amount of C# experience.
I'm creating a SharePoint Web Part, but I'm doing the development for it locally in ASP.NET 1.1
I'm using a DropDownList control with autopostback = true in order to run code on the SelectedIndexCh anged event. Both IE 7 and FireFox are obviously loading a page again when a selection is made, but only FireFox actually shows the changes made to the page.
I tried a simple sample page and noticed the same behaviour, here it is
aspx page
<%@ Page language="c#" Codebehind="Fak eFormToCodeStea l.aspx.cs" AutoEventWireup ="false" Inherits="WebPa rtTester.FakeFo rmToCodeSteal" debug="True"%>

Any help would be much appreciated
