Hey, As a matter of fact this exact problem happened to me. Only a few of my applications would launch mostly incapacitating the machine. To fix this, run the upgrade to 10.2.5 if you don't have it just find it on Apple's website. I just ran it over my original 10.2.5 installation and the machine was none the wiser. I believe this is caused by a corrupt file deep in the system that is practically impossible to replace so doing this fixed my computer good as new. Don't forget your permissions fix at the end ;-) CJ On Monday, April 21, 2003, at 10:23 AM, Steve O'Neill wrote: > Help!
