Subject: simple ruby program problem

So I have been reading Chris Pine's book, "Learn to Program".  I am
working through the examples and the "a Few Things to Try" sections at
the end of each chapter.  I having a problem with one of them.

Here is the chapter: http://pine.fm/LearnToProgram/?Chapter=08

Basically, he wants you to write the psych question program w/o using
the variables good_answer and answer.  I tried to do this in the code
below, however, when I run it in TextMate and the gets asks me for input
before puts lists the question.  In other words, the first thing that
happens after I run it is the "Script is requesting input" message box.

I will note this: every now and then, the program will work properly,
but this is usually after I run the program for the first after opening
Textmate for the first time.

Thanks for your help!!


# begin code here
def ask question

  reply = ''

  while (reply != 'yes' || reply != 'no')

     puts question

     reply = gets.chomp.downcase


     if reply == 'yes'
       return true

     elsif reply == 'no'
       return false

     end

     puts 'Please answer yes or no!'

  end

end


puts

ask 'do you like apples?'
wets_bed = ask 'do you wet the bed?'

puts

puts wets_bed

# end of code
