# MkDistr - User Interface.
#
# Jack Jansen, CWI, August 1995
#
# XXXX To be done (requires mods of FrameWork and toolbox interfaces too):
# - Give dialogs titles (need dlg->win conversion)
# - Place dialogs better (???)
# - <return> as <ok>
# - big box around ok button
# - window-close crashes on reopen (why?)
# - Box around lists (???)
# - Change cursor while busy (need cursor support in Qd)
