In V3 interface, I created a new RSS channel. When I click Actions >> Get Rss html code, the code is very briefly displayed (less than 1 second), then goes back to the Details page. I am able to add the RSS channel via Dreamweaver.
I have tested this in both IE9 and Chrome 18.0.1025.162 m
I posted the same issue earlier this year, and received a reply, it's on the Adobe BC bug list but hasn't been fixed yet by looks of it.
Work around is to momentarily switchback to V2 where Get RSS Code does work.
