I'm working through the 'picturebook.rb' example in "FXRuby Create Lean and Mean GUIs with Ruby" and got stuck embarrassingly early in the book. I'm good up to the point that a blank window pops up (p 28). When I proceed to add the other classes (p 30), errors result. The program runs fine as shown, but when the commented lines are uncommented an error message is shown (below). Code that replicates p 30 with four lines commented out: require 'fox16' include Fox #require 'photo' #require 'photo_view' class PictureBook < FXMainWindow def initialize(app) super(app, "Picture Book", :width => 600, :height => 400) #photo = Photo.new("bridge damage10.jpg") #photo_view = PhotoView.new(self, photo) end def create super show(PLACEMENT_SCREEN) end end if __FILE__ == $0 FXApp.new do |app| PictureBook.new(app) app.create app.run end end Error message: C:/Ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in 'gem_original_require': no such file to load -- photo (LoadError) from C:/Ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31: in 'require' from C:/Ruby/myscripts/picturebook/picturebook.rb:5 It seems like the fix would be to path the files so FXRuby can find them, but I don't know what path that would be? Thanks, Jessica

After reading 7.6 in "The Ruby Programming Language" I know what path is searched first. I was running the program with an absolute path, so the other files were not found. Now I'm getting a different error: C:/Ruby/lib/ruby/site_ruby/1.8/fox16/kwargs.rb:1193:in 'old_initialize': wrong argument type Photo (expected Data) (TypeError) The error output continues.
