Andrew,
I am finding that the Login Screen does not function as expected in 2.4 in Flashbuilder 4.5.
For some reason that I can't yet figure out, the config.xml is not loaded the same way as in the earlier sdk after the login is completed, and thus my initial extent of the base map is not honored, and the viewer loads with my map fully zoomed in to the lowest scale, i.e. highest zoom.
I wonder if anyone else has this experience?
Thanks,
Jim Faron
