When you say you can't run the tests without JavaScript / Flash... I can see how JavaScript might be essential, but are you certain that Flash is essential? Perhaps you could specifically disable Flash in IE for these tests. IE handles Flash differently from other browsers, and I find it to be the least stable browser as well. Have you considered using more capable browsers for your testing, such as Firefox? Watir-Webdriver will support most common browsers whereas Watir only supports IE. I can't do much testing without being able to replicate this error. Can you provide a URL which consistently causes this error to appear? -- Posted via http://www.ruby-forum.com/.
