from what version did you move _to_ 6.0.3? perhaps the changelog between the two releases might point at something that's been updated to give you a clue?
also, 6.0.4 has been released http://docs.xamarin.com/ios/releases/MonoTouch_6/MonoTouch_6.0#MonoTouch_6.0.4 -- you might already have been prompted to download that? might be worth trying? alternatively, does downgrading back to the previous MT version you had fix the problem? cd On Sat, Oct 13, 2012 at 11:40 AM, Dean Cleaver < [email protected]> wrote: > James,**** > > ** ** > > I did share the code.
