Comment 1 for bug 1817597

--- the highlighting behavior of the findText()
... does not have any builtin automatic highlight. This can only happen, if you use the Settings.Highlight feature, to auto-highlight all matches found with find, wait and exists.

So this is not a bug, but a consequence, when using highlight before a click, with Gui elements, that vanish, when focus is stolen.

For the other things please post separate questions, one for each different topic.

... and if you reference any other questions and/or bugs, please add a link.
