Great. Thanks for taking a closer look.

It's funny though.  Before I tried simplifying the body, I did
try simplifying the Subject line, by removing the backquote,
the single quote, and the double-quotes.  That didn't fix it
for me.  But perhaps I didn't do what I thought I did.

Anyway, if you've found a fix, that's great.

BTW, it wasn't about having an effect on launching Outlook.
I already had Outlook open.  It was only about not creating
a new Outlook message with the header filled and the body
ready to be pasted as the bug-report text.

(I don't want to try testing this, as that will likely create
a useless bug report.  If you feel this fixes the problem
that's good enough for me, until/unless I run into it again.)
