I've read all of the recent posts about problems with conditional logic. I had a simple set of radio button choices working fine before the most recent update, but now they are not working properly. It will show conditions for the first radio button selection, but then it won't hide this selection when choosing the second, and the third choice doesn't show at all. As I said, these were working fine before the update. I deactivated all plug-ins and it still doesn't work, but does work when I change to the Twenty-Ten theme, so it looks like it's a theme conflict. However, changing to another theme is not an option right now, and it makes more sense to simply roll back for this one particular site for the short term. My email is firstname.lastname@example.org if you want to send me the rollback and instructions.
