Peter,
The function entry-select in ltk.lisp should use downcase in the format string. This is so that you can pass :begin or :end as the start or end of the range. The corrected function is appended below.
Best regards, Sudhir
(defun entry-select (e from to) ;; downcase the from and to indicators (cater for :begin and :end) (format-wish "~a selection range ~(~a~) ~(~a~)" (widget-path e) from to) e)
