Just did one and clicked the submit button and get a page that says:

Your survey has been timed out


??? Don't know how that could happen cuz it was moving merrily along, LOL

http://s4.ktrmr.com/mrIWeb/mrIWeb.dll is the survey URL

I know it wasn't a disqualification issue because the page said "Thank you for completing the survey", and underneath that is the "submit" button.
