IE : warning message about "Sure you want to leave this page?"

[amackay]

Hello,
Your site is amazing! I have been using your page in a widget with iframe, doing a refresh on the iframe once a minute to show different content (cycling between wind/rain/temp).

Starting earlier today it has stopped working and I see a 'Are you sure you want to leave this page' message in Internet Explorer 11 whenever attempting a change to iframe src. Has there been a 'beforeunload' handler added in your javascript? Chrome works fine but I have a requirement for IE. Without using the iframe and just trying to leave https://www.windytv.com I also get the 'leave this page warning'. Is it possible to disable this warning?

Thanks!
Andy

There is more reports of this. Browser should not do it. I will investigate.
