This sux! I was just getting used to the itunes features in lw. 4.0.5 works fine at work, dnld 4.0.7 at home and now nothing! arghhh, this is so frustrating. I've even tried to copy the program from work and transfer at home, but no luck. The icon bounces and then poof, gone. "Application not responding" appears in the dock header when you hold down the icon upon trying to launch.
