Re: Ensure only one instance running

VB.NET has
Microsoft.VisualBasic.ApplicationServices.WindowsFormsApplicationBase
exposed by the Properties page that allows a single checkbox to control
single instance. You can use it from C# by adding a reference to
Microsoft.VisualBasic.dll and inheriting from it...but it might make you
feel dirty. ;)
