problem with capi:print-rich-text-pane

Running the example code rich-text-editor.lisp:

A - If I print using the menus in the example, and the text is all in the
default font, printing works fine.

B - If I change the font or the font size, add more text, and try to print,
then I get a popup window
entitled Document, which says "Skipping page ..." with a page number which
increments very rapidly, but
never seems to terminate. If I click in the X in the upper right corner of
the Document popup window, I get a message from Windows that the program is
not responding. If I say to quit, Lisp terminates, and
after it does, the text is printed properly, with the font changes etc.

C - If I save the text using Save As, it writes the file fine as an .rtf
file, and when I print it (through Microsoft Word), it prints correctly.

I am using Lispworks 4.3.6 on WIndows XP Professional. Can anyone help?

Thanks,
Jim Bushnell
