I live in Hawaii, and my photo subjects are often of much darker
skin and hair ... perhaps this is why I have fewer focusing
problems?

Here is an example of frustration that just happened to me:

Consider the following picture (speed:1/250, aperture: 2.4), speed
priority to reduce OOF due to a slower speed:

Zooming the face of my daughter, you clearly see it is OOF:

Now notice the hair of a my wife on the right side of the photo:

They are actually focused!.

Go figure why the olympus choose to focus on that!.

You hit the nail on the head. My OOFs are because both of my
grandchildren are white with blonde hair.

same techniques with the E 20 I've seen out of focus pictures
increase from 4-5 out of 100 with my E 10 to 15-20 out of a 100
with my E 20. I enjoy the E Series very much, & was OK with the out
of focus frequency with my E 10, but am dismayed by the increase of
the E 20.

What concerns me most sbout the E 20 is this; I have had very
little trouble with my E 10 in the year I've owned it. Using the
same techniques with the E 20 I've seen out of focus pictures
increase from 4-5 out of 100 with my E 10 to 15-20 out of a 100

Well, what I said is true. This is my everyday experience with both cameras. I appreciate the extra resolution & Microdrive support of the E 20, although the 380 Microdrives worked perfectly in my E 10, & the other upgrades but I'm somewhat perplexed on this focussing issue. I talked with Olympus Support last week & their suggestion was to return the E 20 to them. They E-mailed me the instructions for returning the camera.
