In the forum http://forums.codeblocks.org/index.php/topic,23494.0.html user tomay3000 reported wrong grouping between two unrelated radio button sets. This is becasuse the first radio button of the second group should have the wxRB_GROUP flag activated and it is not.
This patch fixes this. The patch has a lot of unrelated changes, they are made by wxSmith rearranging things.
Thank you! fixed in r11874
