Change default color of timeline layer?

[Sasha99]

Is there a way to change the background color of the layers the Flash timeline itself?

I'm using XP, and there is not enough difference in the color of a selected layer and one with extended keyframes that is not selected. At school I use a Mac and there is definitely a blue vs. a gray. On my computer, they are two very close shades of gray.

Thanks.
