Using OCRA, FXRuby and pdf-writer problem

Hello all,

  I made a simple salary calculator as practice using FXRuby, OCRA to
create an .exe file and pdf-writer to generate a small "report" with the
results of the calculation.  The program runs fine when run with the
ruby interpreter, although I get some warnings:

--------------------------------

  I noticed that when I run this code with rubyw, it does not execute,
but with ruby.exe, it runs fine.  Am I doing something wrong?
