I went to a WEB page and did a Descendant Report.
First I used Firefox and it went into forever loop. So I switched to Chrome and the results were basically the same.
I get a box with 20 in it and some rotating spokes which rotate forever.
With Firefox I can click on the Export PDF button and it did something. I was also able to scroll down the page and look at the Descendants.
With Chrome I could not click on the Export PDF button and I could not scroll down and look at the accumulated Report on the WEB page.
