(I'm sorry, I can't see anywhere starting with "Labels:" below, so I couldn't add a label starting with "Optimize-")

What command do you run to optimize the PDF?
pdfsizeopt --use-multivalent=false M:\Training\Poisson_workshop\dnap.pdf

What does pdfsizeopt display when running the command above?

(I'm sorry, I couldn't seem to work out how to use Subversion to get the Windows version of pdfsizeopt. But I downloaded pdfsizeopt yesterday from the place indicated in the installation instructions (http://bin.pdfsizeopt.googlecode.com/git/pdfsizeopt_win32bin-v3.zip) so it should be whatever version that is.)

What's wrong with the optimized PDF?
When you click on A, B, C, D, or E in the PDF nothing happens. Looking at the Layers thingy in Adobe Reader, there are five layers present, but they are somehow linked: clicking on the box for one layer makes all the layers visible or invisible.

What should be there in the optimized PDF instead?
There should be five separate layers. None should be shown when the PDF is open, but each of the letters A, B, C, D and E is associated with one of them such that that layer is made visible and the other layers made invisible when that letter is clicked.
