Update!
I updated the source code quite a bit. The major change was I switched out the background workers to timers. The way I got how the panel's blink is from JMcIlhinney's thread here. Also, you don't need to add any controls to your form, you can just copy and paste the source code and it should compile. The only thing I'd look for if you do that is to make sure Visual Studio's doesn't remove the Form_Load event handler. Also, another thing that I've made sure to do is to properly comment my code.
