You're right - there are no methods defined for scrolling-fred-dialog-items.
Here's the result of inspecting the ccl::window-hardcopy function:
#<STANDARD-GENERIC-FUNCTION WINDOW-HARDCOPY #x2808AE>
Arglist: (WINDOW &OPTIONAL (SHOW-DIALOG? T))
Methods: (#<STANDARD-METHOD WINDOW-HARDCOPY (FRED-WINDOW)>)
And the standard version doesn't know how to print any other windows.
If you want to define your own methods for printing the contents of
a window (print-contents), I've contributed print-utils.lisp to the
contrib directory. This includes methods for printing windows
window-hardcopy which recursively prints the subviews of the window
after drawing a box the size of the window. The subviews are drawn
using print-contents. Print-contents is defined for
You can add other print-contents routines to print other types of
views. The window-hardcopy routine supports reduction/enlargement,
treating fred-windows separately from non-fred windows.
