I have cforms 14.2 installed, with a cform contact form as a widget in the right side panel. Cforms has not had a version change. I'm on WordPress 3.6.
I use Widget Context to make this contact form only visible on the "Enquiries" page.
When I use Widget Context 0.7.1 everything works fine.
When I use Widget Context 0.8.1 the contact form appears on every single page, even if I tell Widget Context to "Hide Everywhere" for it.
If I drag the cform widget into the "Inactive Widgets" area, it removes it from ALL pages - including the enquiries page.
I use Widget Context for other text widgets in the right side panel, and they are fine in 0.7.1 and 0.8.1.
So I think Widget Context is broken with cforms in WordPress 3.6.
