Can't drag/drop html file into browser now

[RobStevenson]

Hi,

It might be a MacOS issue, but I thought I'd ask here first because I'm more likely to hear from knowledgeable people, and from people who may also be having a problem even if it is OS related. I primarily edit html files on my iMac using BBEdit. (Assume the latest versions of everything.)

As of sometime in early October this year I could do what I've done for decades, drag a file from a folder open on my desktop into a browser window -- either Safari or Firefox, often both -- to view before, during and after editing. Once satisfied I upload the file to the server using Transmit. Today, for the first time since early October, I tried to drag a file into Safari and nothing happened. Curious, I tried Firefox -- again nothing happened. In either browser I could use command-O to open the file.

The only conceivably relevant happenings between October and now is that I updated to the latest Catalina (I had a slightly earlier Catalina in early October), and similarly updated to the latest BBEdit (though why that should matter I can't imagine.) BBEdit is mapped in the OS to open all html files, which is the only connection I can see.

Has anyone else seen this? Any hints?

Thanks,

Rob
