Slider thumb pictures blurry

I just wanted to share what worked for me. I noticed that the slider thumb (with custom png graphic) looks sharp when the mouse hovers over it. If this is the case for you, then try duplicating the hover state, and name it Selected (or any of the SL built-in states). Then add a trigger to change the state of the slider to Selected when the timeline starts.

Correction: I realize that you actually need to create a Visited state, NOT Selected state. It doesn't really work with a Selected state, because every time the user interacts with the slider, the thumb graphic toggles back and forth between the Selected (sharp) state and the Normal (blurry) state. With the Visited state, the image stays sharp.
