I am trying to use the fltk::VTKImageViewer (fltkVTKImageViewer.h) and I was wondering if there is a good example to look at. When I call Show() the window pops up, closes and then aborts. Thanks. -darby j --------------------------- Darby J Brown SCI Institute University of Utah Email: darbyb@cs.utah.edu Phone: 801.587.7878 ---------------------------
