I've been working on a project that has a few UserControls, all put onto my main form. Recently one of my UserControls has changed into a class (icon in Solution Explorer has changed). I can no longer edit the Designer (GUI) of it. Why has this happened. I first noticed it when I opened the program for edit last, it opened all the window tabs that I was using before (including the GUI designer for that UserControl). When I would double click on an object in that UserControl (in designer mode), it would take me to the Designer text code, not my actual code and everything in my actual code stopped working, and it would only execute subs written in the designer code. What is going on here? How do I get it back?

Thank-you for your help!
