Some ten days ago, I sent a mail with subject:
newbie: class with display works only one  instance at a time
Referring (in brief) that trying to use several DiplayImpl2D in a GUI 
based on JInternalFrame's I was not able to have more than one 
display appear at a time.
I solved the problem, or at list got around it, by spawning a 
heavyweight Frame for each display. Dod other encounter the same 
problem? Or is this a general characteristic of VisaD, to show only a 
display for each heavyweight container?
Ciao
Francesco
