Tip: Working with the taskband and the flash button.

[Panda X]

The open app button on the taskbar shows if an app is open and if it's requesting attention. In Vista it used a whole different image. Due to this, you can't have an opaque open application button it has to be transparent or a very faded translucent.

I made an application to make a video to show how it works: http://media.longhornfusion.net/FlashButton.swf
