Lonetrekker,
Thanks for your answer. I almost never burn anything - maybe once or twice a year when I have a new piece of music ready to go to CD. And, besides, it is not a matter of seeing space of any amounts taken from me. It is the file numbers ever increasing, when I see them statistically listed when using the disk utility to repair any permissions.
I tried the derien utility offered earlier. It did not show any unusual file sizes for the files that were listed in the App folder, nor any files I might not have expected to be there.
I am thinking of going to see a genius at the Mac store.
