Well I ran into monstrous problems with my phone and so have factory reset and re installed stock rom. I am now re-rooted and working. I started B4Abridge and the designer installed but I am still having the same problem and no, b4a designer isn't in the list of apps when I get the "complete action using".
However I have just noticed if I run the designer manually first then I get the layout so I can work with it. It would be nice to get rid of the "complete action using" scree though.
