I got to wondering why people lose checkbox settings as often as they do. I've never 'believed' the suggestion often proffered… updates to new versions sometimes overwrite random configuration settings.
An obvious culprit is by inadvertently pressing the accelerator key sequences (i.e. on Windows that's Alt+'x', where the 'x' is underlined in the prompt). So I went into Preferences->Look and Feel->Main Interface and tested them. The following shows the ones that are not working as I think they should:
The prompt (e.g. "Show
tooltips in the book list) lights up, but the check box doesn't toggle on/off, same for the other two I've marked.
For some, it appears to be related to having the same accelerator key sequence used for multiple fields - e.g. Alt+T -- "Show
tooltips…" and "Use
two lines for the…",
But I can only find one Alt+D -- "Allow using
drag and drop to…"
I tested a couple of the other preference dialogues and found what i think are similar problems.

given how few people actually use accelerator sequences perhaps there could be a toggle to disable them -- Qt permitting of course.
