We it looks like, in the ConfigManager, that IE doesnt like executing multiple subscribe events simultaneously. By changingdojo.publish("configLoadedEvent", [this.configData]);
to dojo.publish("controllerConfigLoadedEvent", [this.configData]);
dojo.publish("widgetmanagerConfigLoadedEvent", [this.configData]);
dojo.publish("datamanagerConfigLoadedEvent", [this.configData]);
dojo.publish("mapmanagerConfigLoadedEvent", [this.configData]);
and adjusting the corresponding listeners, and since it is synchronous, you are able to specify the order to make it load properly. hope this is helpful to anyone still using this.
