On Safari and IE, both browsers always 'unexpectidly quit' when I try and do certain downloads! And it is really annoying! One download that I just tried to do was QuickTime Broadcaster. Once again, Safari and IE crashed. But if I try with FireFox, it works! I have tried restarting but that has made no difference. Yet some downloads in Safari and IE will work! I have just installed Mac OS X 10.4.6. Is it something to do with that? PLEASE HELP THIS IS REALLY FRUSTRATING!
