Update Close Window (partial title)

This will get the hWnd of freaky programs that change class names every time you start it, and then close it. The only thing you need to know is part of the Titlename (Netsc, instead of "Web Page Title" - Netscape). This WILL close Microsoft Internet Explorer (old version wouldn't) now =Þ. Also, I made it so that you don't have to have a form named "Form1" (by using EnumWindows)
