Thank you so much for the prompt and ON-TARGET response!

This begs a question: Does anyone know the current stats for Windows users bit-depth settings? What percentage of Windows users are set to 16-bit? 32-bit? 8-bit?

Cheers!

This is a common issue with systems displaying 16-bit color (thousands). And
that is because 16-bit color is just not adequate for handling alpha
channels. Change your display settings to 24 or 32-bit color (millions).

due to the emulation of Virtual PC? But that would be odd, because Virtual
PC has always been spot on with its emulation in the past, for everything
else...

the Windows 98 environment when displaying using IE, FlashPla (v5) and
SAFlashPlayer (v6).

No, I don't know the current stats. You might try http://www.webmonkey.com to
see if they have some. A couple years ago, the figure was something like 80% had
800x600x16, but I would imagine that's changed pretty dramatically given the
development, since, of a lot of higher quality graphics cards and the price drop
in monitors.
