I need to rewrite this at some point, it was a quick-fix and doesn't 
currently have failsafes. Anyway, this is what I'm using:

____________

@download_directory = "#{Dir.pwd}/RubyDownloads"
@current_downloads = Dir.entries( @download_directory )

  def wait_for_download

    #Find the newest file
    difference = [1,2]
    until difference.size == 1
      difference = Dir.entries(@download_directory) - @current_downloads
      sleep 0.1
    end
    file_name = difference.first
    puts "Found new file: #{file_name}"

    new_size = 0
    current_size = -1

    #Wait for file size to stop changing
    until current_size == new_size
      current_size = File.size("#{@download_directory}\\#{file_name}")
      #puts "current file size: #{current_size}"
      sleep 0.1
      new_size = File.size("#{@download_directory}\\#{file_name}")
      #puts "new file size: #{new_size}"
      sleep 0.1
    end

  end
