Cancelling the preferences dialog still makes changes to the preferences

[sparkhi]

Steps to reproduce:

1. Launch preferences
2. Uncheck one of the zip processing
3. Click "Cancel"
4. Open preferences again, the checkbox from step 2 remains unchecked (i.e. unknowingly some setting has changed - BUG)

Seen as far back as v6.5.2

Thanks. This is interesting. It looks like the subtle difference between the Cancel and OK buttons is that if you press OK the settings survive a restart of the application, whereas if you press Cancel they apply during the session but don't survive a restart. Not as intended though, as you say.

It looks like the setting change does not take effect, but it is misleading to the user.
