Note: I found that using a normal TPanel almost works. I can prevent it from being skinned, but then Alpha controls (like TsComboBoxEx) that are placed inside the TPanel have rendering problems when they get skinned (subtle pixel errors around the corners, that only appear if the Alpha control is inside the TPanel). So, as a solution to my initial post, the TPanel would work if it weren't for the rendering issues. But if there is another way, please let me know (such as using a TsPanel while making it “transparent”, if that's possible).
