Watir-webdriver timing out when asked if element is present?

Question

Ruby 1.9.3p327
watir-webdriver 0.6.1

On a fresh Ruby install, with a fresh webdriver install, I am unable to use wait or present? with nonpresent elements without causing non-Watir Timeout errors.

In the below example, id 'gb_32' is on the page, but hidden. Id 'gb_50000' does not exist. In both cases "present?" should return false, but the second one gives me a timeout error after 60 seconds. Any ideas why this could happen?

    irb(main):014:0> b.link(:id,'gb_32').present?
    => false
    irb(main):015:0> b.link(:id,'gb_50000').present?

Thanks.

I managed to put together a kludge for now by using explicit timeouts in the "present?" and "until" methods. Something like this: Timeout::timeout(input_timeout=1) do; #Default webdriver command here; end; rescue Timeout::Error; raise TimeoutError; end — Virtuoso
I think it's down to the network driver. The page I was looking at was "www.google.com". The fault still appears on "about:blank" when I try looking for exists? or present? for nonpresent elements. — Virtuoso

I'd add this as a comment but evidently I can't yet. Are you using Firefox 17? Watir-webdriver isn't yet compatible with 17, so if you are then try reverting to Firefox 16 and see if your code works. I understand that a watir-webdriver update to resolve this compatibility issue is being released next week.
