As far as I can tell there are two separate errors here---the "Apply"
button should work the same as "Okay" (only not pop down the window
at the end), but instead it seems to do nothing.  The other error is
that there is an element that gets selected while the routine parses
the contents of the schematic, and this element remains selected
afterword.  If you click the right mouse button in the schematic window
to unselect everything before hitting "Okay", it will generate the
symbol view.  I will of course have to track down the segfault condition,
but this will let you continue without crashing the program.

I have not yet attempted to verify the "load dependencies" problem.  I
will let you know if I need more detailed information about how you
set up the schematic links.
