I re-created the visual 'effect' (I had worked around the problem and deleted 
the originals). Attachments sent to Matthias off-list.

I've now looked at it differently. Seems the converted PNG is OK. It's the 
'included' SWF that renders oddly. It *might* be a problem with how the 
browser renders the SWF. Or how swfc 'includes' an SWF.

Hmmm. The more I look at it, it might just be the way the plug-in renders the 
image. (The rendering is the same whether I use Mozilla, Netscape or 
Konqueror.) The apparent 'doubling' of the left and top column/row seems to 
shift to the right and bottom column/row at larger scaling.

Don't you just hate when you find out, after complaining about a problem, that 
you've gone to the wrong office? :)

Thanks for the assistance! I'm slowly getting the new splash intro done. Now 
if I can only figure out how to make audio work, I'll be all set!
