As often happens, Magic Banana's constructive suggestion solved the
Pesky-Popup
problem. I went to my .config file: cd /home/username/.config, then listed
its
contents. Next, I plodded through the list of files and directories, each
time
entering sudo mv filename filename.bak, followed by clicking on either my
Home
folder or my Desktop folder. Unsuccessful, I'd change each one back again
before
going on to the next one.
Halfway through the file listing, sudo mv mimeapps.list mimeapps.list.bak was
the key: No more sendmail popup ! I was shocked to see the contents of the
chosen
folder instead, for the first time in a couple of weeks ...
I "fixed" mimeapps.list by commenting out the four lines:
> cat mimeapps.list
> [Default Applications]
> # inode/directory=icedove.desktop
> # text/plain=abrowser.desktop
>
> [Added Associations]
> # inode/directory=icedove.desktop;
> # text/plain=abrowser.desktop;
Now I can view the contents of those folders as well as many others without
any roundabout workarounds.
It remains a mystery why one or more of these lines was invoking those
popups.
I'll uncomment them one at a time and report back; of course, it could be a
combination ... which would take a little longer.
Thanks,
