Computer is a dual 1 GHz G4 mirrored doors (first generation, with the fan/power supply replacement installed). I'm running Panther (10.3.2, with all updates installed. I posted a question earlier about this problem. I've done a bit of investigating but haven't resolved the issue. I think there's something significantly wrong with the totality of software on the boot drive. There's one other problem that makes me think this, namely that an innocent TextEdit file makes ITS parent application crash-quit. It's the ReadMe from the DiskWarrior 3.0 CD, and the same file can be read by TextEdit on my Al-15 PB. I made a clone of my boot drive with CCC 2.3. The clone performs just as did its original (both the Adobe Creative Suite installer and TextEdit crash as described earlier). I've replaced the boot drive's directory using DiskWarrior 3.0. This didn't help either. My next option (groan) is to re-install EVERYTHING from scratch onto the mirrored door G4's boot drive. There are a few other reasons to do this (such as correcting allocation of licensed software on my network so that everyone will have a properly licensed copy of everything we use - I used the wrong serial numbers in two instances, so that sometimes one or another user on our LAN is denied access to Office or to Virtual PC. However, this is obviously a Herculian task and I've put up with inconvenience for quite some time because of it. The one remaining thought I had is that perhaps I have a corrupt font that is causing this. I have Suitcase X installed on the boot drive. Is there any likelihood that examining all my fonts might help? Any other suggestions? Jim Robertson --
