Not sure what happens in your example, but this shows something
interresting:<br>

<br>
It seems that a PNG8 is using a palette (obviously), and it can include
both an alpha mask, and<br>
a gif-like transparent "color". If your browser, or MapGuide, only
supports the transparent "color",<br>
it would look like your example.<br>
<br>
Have you tried this in FireFox?<br>

Well [unless I'm misunderstanding something] that's what I put in the
opening post of this thread. What I want to know is why using PNG8 for both
causes the latter to lose transparency.
