I've had my Mac for six days now and love it. Yesterday, while playing WoW, I experienced my first crash (it was the video freeze). Just moments ago, however, I experienced a second one that confuses me. I had a Finder window open and plugged in a USB drive, causing Finder to become unresponsive and I am unable to reboot via the apple menu. I tried to force-quit-restart Finder but the top menu bar is still frozen (save when I open an app). I have Safari open now and can select restart...it just doesn't do it. I'll do a hard reboot in a moment. As a long-time Windows user, when Explorer crashes, I simply kill it and start a new instance. Is there a similar technique with the Mac? Thanks!
