The WoW radio button as seen in its native habitat (see the Create Auction window at the Auction House) is smaller than its check box cousins. The CheckBox widget for AceGUI does not account for this. It also has an incorrect TexCoord value for the "check" texture--the active radio button should have a small yellow circle, not a large blue one.
I may be an Ace noob, but I'm an OCD Ace noob ;) Is this something an Ace guru should fix, or should I submit code changes? And if the latter, to where/whom and how does it get peer-reviewed?
