FXRuby 1.4.6 works fine except I call FXFileDialog.new. My enviroment is : windows 98 cygwin version 2.427 ruby 1.8.1 (2003-12-25) The program I ran is foxhello-1.4.6.rb : #require 'rubygems' #require_gem 'fxruby' require 'fox14' include Fox theApp = FXApp.new theMainWindow = FXMainWindow.new(theApp, "Hello") theDialog = FXFileDialog.new(theMainWindow, "filedialog") # this is line 10 The result is : $ ruby foxhello-1.4.6.rb foxhello-1.4.6.rb:10: [BUG] Segmentation fault ruby 1.8.1 (2003-12-25) [i386-cygwin] I also run the same program using FXRuby 1.2.6, it works fine. Is this is a bug of FXRuby 1.4.6? Best ragards, uncutstone -- Posted via http://www.ruby-forum.com/.
