This is most unusual. First-Specs of Computer. 2.16 MBP 2GB Ram 100GB 5400 rpm HD OS X Tiger 10.4.7 I was downloading a trailer from ign.com, reading a translated script, had Mail open, and suddenly my mouse cursor disappears! Not only that, but I couldn't put the machine to sleep. I closed the computer to see if it would sleep without using the power button. It just stayed on in a frozen state! I have my firewall on and all sharing options disabled. Was my computer hacked into and frozen or was it just a fluke? Just reading a script online and downloading a trailer from a known site couldn't just freeze things? When I did cold-boot my computer, I noticed the trailer finished downloading via Safari. I didn't see the message where it asks me to continue downloading the item. Perhaps Safari just crashed my computer?
