Only the screenshot examples (still images) work, the interactive
applets show up a gray square only.
I googled around and found that there seems to be a problem with Jmol
and OpenJDK, see http://wiki.jmol.org/index.php/Release_Procedures and
http://www.mail-archive.com/[email protected]/msg11590.html
and the thread following it.
So I install sun-java6 (jre, plugin and where they depend on) and now
the interactive applets from the Jmol website work. But plot3d in a
workbook of Sage notebook only produces a black square with "Jmol" in
the lower right corner. Rightclicking in the square opens the Jmol
menu. If I click the link "Get Image" (outside the lower right corner
of the square) a firefox window pops up and starts loading something,
showing the black square (with "Jmol" in the lower left corner) and some
text "To save this image, you can try right-clicking on the image ..."
and keeps loading forever.
But strange: If I open the tutorial inside a notebook (help ->
Tutorial) the plot3d examples do give the interactive Jmol plots and the
"Get Image" click pops up a firefox window with a still graphic, but
keeps loading forever, too.
This or similar behaviour has been described on sage-support several
times, but afaIk without solution. Any new ideas?
Thank in advance
Eckhard
