Since I have a invalid XAML problem that my doctor can't help with, I decided to just willie-nillie click about for a bit. Little did I know that it would end up in an adventure of opening and closing applications. This software is without a doubt, full of suprises!
I double clicked a js file, it opened up Notepad.exe. I then went for a html file, and it opened up Office 2007. Then a .cs file, and it opened up Visual Studio 2005. I think Blend must hate VS 2008 because that sucker was already open, but it just totally ignored it. Man, my apps can't even get along, sorry Rodney King.
At least now I have 5 applications open instead of the original 2. I went ahead and opened up Disk Defragmenter, Outlook, and Firefox just to be safe.
