The selection indicator boxes of all tested options under AutoCorrect Options and Options behave strangely. Some display an empty box regardless of whether selected or not. Some display an empty box or a ticked box as expected but the way the tick appears and disappears is unexpected.
In more detail ...
Under Tools → AutoCorrect Options → Localised Options, both quotes' Replace boxes were shown as cleared but experimentation showed replacing was happening. Clicked in the boxes (the box briefly went grey and then back to white) after which experimentation showed as if they were now cleared.
Under Tools → AutoCorrect Options → Word Completion, "Enable word completion" behaved the same as "Localised Options → both quotes' Replace" but the selected/de-selected state was shown by the sub-options being greyed out or not. "Collect words" behaved similarly.
Under Tools → Options → Language Settings, the strange ticking behaviour seen was under "User defined dictionaries" and Options. More detail later because our Internet connection is going down now.
This is on a fresh installation of Slackware64 14.0 on a system that was previously running Slackware64 13.37 and an earlier version of LibreOffice where the options dialog screens were behaving normally. The package was downloaded from http://slackware.com/~alien/slackbui...ce/pkg64/14.0/
and checksummed before installation.
