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:

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.
