Focus box anomoly (continued from prior IE alpha issue)

Question

The "standard" PNG fix for IE doesn't work when there are
JavaScript image
swaps on the page.
The "Fix" for it causes the transparent background to 'flash
white' for a
second as the image loads.
Anyone know of any other fixes?
Here's an example.

Works fine in FF, but you'll see the image background of a
second in IE.

Wow...not REALLY not paying attention today.
Meant to post this here:
Let's start off with my confession that I haven't a genuine
clue about how
this focus stuff works.
Focus box/lines stuff seems inconsistent all over the place.
Some sites show
them, some don't (even without "scrubbing" code) in both IE
and FF. Safari
doesn't seem to ever display them, but I have that by
hearsay, only.

The four graphic links across the top of this page will
display focus boxes
when clicked in FF or if you tab through them, but the "moth"
link at the
right doesn't show the focus box on click or during a tabbing
cycle and
during the tabbing cycle there is a point where the focus box
highlights the
entire page.
In IE6 clicking on any of the links will NOT produce a focus
box, but the
focus boxes DO appear during tabbing INCLUDING the 'moth'
link at the right.
What are the words of wisdom regarding focus box display
cross browser?
