Cornelius,
I probably should have taken another moment or 2 before posting my reply. Now that I have taken that moment, I DID have a few minor problems with "Archive & Install" over Tiger. Specifically, many of the Tiger versions of the Apple applications won't run under Panther, but the Panther installer won't overwrite them since they are newer. So, I had to trash them first. But, silly me, I had already applied the 10.3.9 combo update, so had to do another "Archive & Install."
Oh, well. Did get Panther back, and I've not regretted my actions in the least. Happy to be rid of Tiger!
