=begin
A user reported to Ruby-Talk and RubyInstaller mailing list some issues using ruby 1.9.1p243 (2009-07-16 revision 24175) [i386-mingw32]

http://groups.google.com/group/rubyinstaller/browse_thread/thread/e5e47aabf09aff98

I could reproduce the issue across multiple versions of 1.9.1 and with close-up-to-date version of 1.9.2dev:

http://groups.google.com/group/rubyinstaller/msg/dae727305e57ba6d

Simple test script:
http://pastie.org/786354

require 'win32ole'

t = Thread.new do
begin
ie = WIN32OLE.new( "InternetExplorer.Application" )
ie.visible = true
ie.navigate( "http://google.com" )
puts "OK"
rescue Exception => e
puts e.class
puts e
puts e.backtrace
end
end

t.join

Generates this:

Both mswin32 and mingw32 generates the same issue.

Could you try ruby 1.9.2dev (2010-01-23 trunk 26383)?
I'm not sure fix this issue or not, but the script
works fine in my Windows XP.
I have tested cygwin ruby and mswin32 ruby.
