What do you mean by background? Have your changed the paper colour to the
exact same colour as the web page background? IME this is necessary if
you want to use the Bitmap export to create a transparent bitmap.

Is that 'Transparent background (masked)'?

That's probably because you haven't matched up the paper colour with the
web page bgcolor exactly.

You could instead save a sprite of the blue text against a grey rectangle
and use Intergif to then select the grey as the background colour and
create a transparent GIF. I found this solution when getting as
frustrated as you. ;-)
