Can't drag-and-drop into SNS 2.4

When I ran SNS-HDR today it told me there was an update to 2.4. So I downloaded and installed.
Now I can not drag-and-drop from Adobe Bridge into SNS-HDR. I can drag-and-drop in all other ways so I don't think it's a Windows 10 (1809) problem. Plus, I can still drag-and-drop from Bridge to an older version of SNS-HDR. All other functions of SNS-HDR are OK. I can open files from within SNS-HDR, just no drag-and-drop.
