I hope I got this in the right place since a few different forums might have been applicable. I have an iMac, 21", it's about 14 months old, I've done all the updates it told me to but I can't remember what version I have and I can't find out. A few times it has frozen where the mouse works but nothing else happens, you can't click on anything, but it usually goes away w/ a restart. But now it's not going away. I was just browsing the web, and it froze. I was playing a video on youtube, and the video continued to play until it was over but nothing would happen when I clicked on the close buttons or any other buttons. I couldn't do a force quit becuase nothing is responding. But the mouse is moving. I have restarted and even unplugged 4 times now, and it's still happening. Thanks in advance for any suggestions.
