I have a 2.0 ASP.NET web form. I am using VB.NET. I have a web server button control on the form, btnSubmit. I also have a lot of server validation controls on the form to validate the fields.

--------------------

1. When I run the form using FireFox, everything works perfectly.

2. When I run the form in IE and click the button, there is no post back to the server.

What could be causing this? I thought it might be the javascript generated by visual studio on the page, but there are no errors in the javascript according to FireFox's firebug. I also doubled checked the html on the page to make sure there are no errors.

I was reading that this was a bug in .NET 1.1 SP1, but this is 2.0. Any ideas on where to start?
