"Hyperlink" dialog (CTRL-K).
"Document" tab.
I click on the bullseye to add a "Target" to the form "Target in Document". 

"Target in Document" dialog appears. 

[A] the "Target in Document" window appears over the "Hyperlink" window covering the form (and also the tabs) so I can't see what happens when I select a target; 

[B] selecting a target with a single click doesn't add the target so I can just click "OK" (instead of "Apply, then OK"). 

If [A] and [B] are corrected, then I could see the content of the form "Target in Document" updating when I click on the target, so then I click ok, ok, and move on. 

This may look trivial, but is related to 
https://bugs.documentfoundation.org/show_bug.cgi?id=86845
and 
https://bugs.documentfoundation.org/show_bug.cgi?id=90496
, 
so now contributes to great overclicking.
