We've noticed a compatibility issue with a Silverlight 3 app which runs fine with v3.0.40818, v3.0.50106 and v4.0.50401 but refuses to load in v3.0.40624. Instead it gives a message box saying a more recent version of Silverlight is required.
Does anyone know what the changes were between 3.0.40624 and 3.0.40818 or why the app might not be compatible?
