A friend of mine has a relatively new Core 2 Duo MacBook Pro (15 inch) running the latest version of Tiger. He says that Eudora, Word, Powerpoint and a few other programs crash somewhat frequently while he's working on the machine. Eventually, he says the entire system will freeze and lock up. He can't even get to force quit and is forced to hold the power button to reboot the machine. Since I don't have immediate access to his computer, I don't have a ton of details of the problem but I was wondering if someone had a quick fix or at least a suggestion as to what could be happening. I told him to repair permissions and reboot but it didn't help. Should he bring this machine back to Apple? Thanks.
