closing browser error - change behavior

Question

I'm experiencing some strange behavior with Watir when I want to close the browser.

brs = Watir::Browser.new
=> #<Watir::Browser:0x1035fc1f8 url="about:blank" title="">
brs.close
=> true
brs
NoMethodError: undefined method `closed?' for nil:NilClass

The browser is closed properly (as expected) but after that I'm unable to operate with the class / instance.

Why is that happening?

Answer 1

I am not getting the error message:

$ irb
