Opera (8.most.recent) is easy to convince (I remember I had the same  
problem getting Petri nets going). Make sure that in C:\Program  
Files\Opera\program\plugins you have the following files:
  - Squeak.exe (any recent will do)
  - Squeak3D.dll (provided by the installer, I think)
  - NPSqueak.dll (same)
  - SqueakFFIPrims.dll (any recent will do)
  - SqueakPlugin.image (this one has magic)
The latter can be refreshed from
  - http://squeakland.org/installers/SqueakPlugin.image.zip
It does not matter where the above files come from, you can copy them from  
Firefox's or IE's directories, they don't know which browser vendor they  
are working for and the browser vendors believe that the NP prefix in  
NP*.dll is magic.

I also made sure that my Opera*.ini knows about

Files\Opera\Program\Plugins\NPSqueak.dll,NPSqueak,sts,|Squeak Source  
Files\Opera\Program\Plugins\NPSqueak.dll,NPSqueak,pr,|Squeak Project  

Since the time I did the above the Petri nets work for me, so I was  
surprised that other people do see the "golden" navigator panel. But now  
that I learned that it does NOT appear in your case I can sleep much  
better :-)

Thanks for sharing your experience.
