following example do not work correctly with my ruby 
(ruby 1.4.5 (2000-06-26) [i386-mswin32])


Thread.start {
   print "ok\n"
   print File::readlines("index.htm").to_s  
}
readline


It prints "ok" but nothing else.
If I comment out the "Thread.start {", then it works.

What's wrong?

Thanks
Michael
