Ruby 1.9 enforced the original intent for case statements. The syntax is supported in 1.8, along with the variation that everyone seems to use (at least everyone with a C/C++/C#/Java background). The case statement should be written like this:

1. do something
   end
   end

If you replace the colons after the value on the “when” lines with the word “then” the code should work. Submit a bug report to the watir folks to have them fix the case statements for the next version of the library. The “when X then” pattern works in 1.8, and is forward compatible so there shouldn’t be too much drama with it.
