Help! My window application won't close.

[Alpha]

I have a Window based application that shows up still running in the task
manager when I close it. It reaches the "this.close" statement and then it
stops at the "}" at the section of the following code after the
"Application.Run(new VMSMain());":
[STAThread]
static void Main()
{
Application.Run(new VMSMain());
}

I can't figure this one out at all. I would really appreciate some help
with this one.
Thanks, Alpha

Ok, I found the error. I put the "this.show" at the wrong place. It was at
the end of VMSMain(). I removed it and it works fine now.
