#
# o Ugh. AFter updating to the Bind() method, things lock up
#   on various control clicks. Will have to debug. Only seems
#   to happen on windows with calendar controls, though.

#
# o Lockup issue clarification: it appears that the spinner is
#   the culprit.

This control provides a Calendar control class for displaying and selecting dates.  
In addition, the class is extended and can be used for printing/previewing.

Additional features include weekend highlighting and business type Monday-Sunday
