Failure to run using IE11

No prob using other browsers, but under IE11 all I get is a blank screen.
This just started today.

You can often correct IE problems by enabling Compatibility Mode. To the right of the URL box, there’s an icon that looks like a torn sheet of paper. Try clicking there and reloading the page. You can permanently enable Compatibility Mode for a site from the Page menu.

Yup, that fixed it!
