.NET program -> activex control in IE

Question

Hi all, I have a .NET program already written and I am trying to integrate it into a webpage. I created a new control into my solution and I can display it properly into my web page. Now, when I am changing the HTML code and pointing to my app's main control instead, IE gets stuck and shows nothing. Do you guys know any way of troubleshooting this (or even what the problem is)? By the way, my program is a patchwork of several dll's that I merged with ILMerge (http://research.microsoft.com/~mbarnett/ilmerge.aspx). Thanks in advance for your help, Tony
