[Wtr-general] changing watir versions

[Jeff Fry]

Hey, y'all.

I'm trying to use a feature that is in v1.4.1 but not in v1.1, and find 
that even though I've installed 1.4.1, when I require 'watir' what I get 
is v1.1:
irb(main):001:0> require 'watir'
=> true
irb(main):002:0> Watir::IE::VERSION
=> "1.1"

Details:
I installed watir v1.1 when it first came out.
Over time, I installed several other versions of watir, up to and 
including 1.4.1, each in it's own directory.
I just tried using ie.url in a script, and see it's not found. 
Investigating, I realize that I'm still using watir v1.1.
I checked my PATH and my registry, but didn't see a reference to watir 
in either spot. (perhaps I missed something in the registry?)
I ran the uninstaller, from the Start menu, but it uninstalled v1.4.1.
I then went ahead and deleted every copy of watir I could find on my 
box...somehow I'm missing the one version that my computer keeps 
finding...v1.1 still mocks me.  ;0(

So...how does my machine find watir? How does it choose between multiple 
installs? Can I tell it explicitly in a script to use a particular 
version? And how can I find the version of v1.1 that my machine keeps 
finding and blow it away for good?

In eager anticipation of using v1.4.1,
Jeff
