Logo-background looks bad

hi,

I am trying to include my companys logo in a prosper presentation
using \Logo:
  \Logo{\includegraphics{LDCLogo.eps}}
(I intentionally oversized it so that you can clearly see the problem)
http://home.t-online.de/~fam.natter/prosper/ReklaMan.pdf

This is probably more a general LaTeX problem, but it occurs
particularly often in presentations.

Also, since eps does not support transparency, I guess I will have
to choose a style where the background underneath the \Logo 
is white, or is there another way?

The pdf, tex and eps files are here:

thanks in advance,
