I use an overridden button for the flat buttons in jsiPodFetch and I had forgotten to call InitializeComponent in the constructor that gets called by the designer. This has the nasty side effect of making the control disappear from the form.
The underlying error was corrected before I released 8.04 but I missed one form when I checked for missing buttons; The form to confirm a new feed.
Old users probably never noticed since they have their feeds configured already, but new users got a modal form without button or control box. Doh!
It is taken care of now and I hope I haven’t scared to many users away from it.
