At the risk of testing the forbearance of those reading this who are more experienced with Mac, I noticed an odd problem with Finder, i.e., when I try to use the "Help" option, a blank window and the life saver icon appears for a split second, then vanishes. I seem to recall that the Finder Help display was where one went to read up on the OS. Any comments or suggestions? (BTW, I did look through the forum for similar threads.) Thanks all.
