So System Events is always available via the Scripting Bridge first thing on startup. This is nasty, but it works.

	SomeClass *someObj = nil;

	// This is a rude and nasty hack. Basically if someObj is nil, just keep checking until you get it.
	while (someObj == nil) {
	someObj = [AppDelegate sharedAppDelegate].somethingIWantFromSystemEvents;

	if (someObj == nil) {
	CBLog(@"Could not get a hold of the thing I wanted from System Events.app. Sleeping for 2 seconds before trying again.");
	sleep(2);
	}
