 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/brows...

 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/d...

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

 <pre><code>
 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
 </code></pre>

 Generates this:

 Both mswin32 and mingw32 generates the same issue.
