OK, I just downloaded a 3.9 image with integrated Seaside from the 
Seaside site.

I filed in some code, then opened a System Browser and navigated to that 
code.  Highlighted the code I want to "do it" with, pressed the right 
mouse button, and...

... no "do it", "print it", or "debug it" menu choices exist.  
Everything else seems to be there, though.

What gives?
