I totally forgot about this little application.
Its called
Taskbar Shuffle. Its a cool little app that allows you to "rearrange the buttons on your Windows taskbar by dragging and dropping them. Allows you to rearrange your system tray icons by dragging and dropping as well."
Its great for times when Windows Explore crashes and throws your applications out of your desired order. Hey I maybe picky put if you work in an IT call centre you have lots of applications open and you prefer them in a specific order then well this free app is priceless.
