The latest update seems to be completely broken.  I can't even guess why this is
happening.

I attempted to visit eBay.  This is the result:

I changed the URL to a direct link for eBay login.  The same "connection is insecure"
message appeared.  Selected the advanced button to force the eBay login page.

This mess is the result:

I downloaded the latest version of Otter and extracted the contents into my Otter
directory.  All old files were overwritten by the new.  I've followed this procedure
with several other browsers.  There was never a problem.

I'd like to keep using Otter Browser.  I hope there is a solution.

On which operating system is that?

All old files were overwritten by the new.  I've followed this procedure
with several other browsers.  There was never a problem.

It nevertheless seems good to test it clean in a separate folder, I'd say?

Thanks Frenzie.  I appreciate the reply.

OK.  I extracted the files into an empty folder.  No change.  Same "connection is
insecure" message.

My experience with computer hardware and software goes back before Microsoft
Windows existed.  I'm definitely an "old man" in the world of computing.

I'm very aware of the huge amount of work that goes into creating a browser.  Maybe
the latest version has a few coding errors that react badly with my operating system.
All previous versions functioned normally.

I'll download the latest version of Otter again.  It's not very likely, but it's possible the
copy I've got has a few corrupt files.  I can't think of anything else.

Otter is a terrific browser.  The authors should be proud.

Unfortunately there is no Otter latest version 1.0.02 for XP

I can use eBay fine with Weekly 360 on Windows XP FWIW.
