I do have another small issue. For now, I have switched back to not using the arrow graphic. I dragged in the original button for the target graphic, but it doesn't look like any of these tint options are working. The buttons are just staying one color the entire time.
Make sure the Button's Target Graphic field points to the correct Image -- that is, the one on the Button itself, and not a different one. Other than that, no other common issues come to mind.
