Rails - Sep 2008 - inheritance fail.

Hi guys,
I''m building a class that handles functions for both IE and FF.
The trubble is that when I pass a class (e.g. for IE), I can''t use
normal functionality.
A wee example below. the browser.goto("http://www.nu.nl") command
fails.

class BIE <IE
	def initialize
		#@ff = FireWatir::Firefox.new()
		#@IE = Internetexplorer.new()
		@strBrowserType = ''IE''
		@browser ||= Watir::IE.new; @browser.speed = :fast
		puts "new IE instance"
	end

	def talk
		puts "talking IE"
	end

	def ggoto(url)
		@browser.goto(url)
	end
end

class Browser

	def initialize
		#@browserIE = new BIE
		#@browserFF = new BFF
		@strBType = "FF"

		#@browserIE.retrieveSettings()
		#@strBType = @browserIE.getBrowserType()
	end


	 def BrowserChoice()
		# case select
		  # what browser in start.xls
		# end
		puts "in browserchoice"
		 test = BIE.new

		 return test
	 end

end

#option 1
	b = Browser.new
	browser = b.BrowserChoice
	browser.talk()
	browser.goto("http://www.nu.nl")
