When setting the slider of the "unlock difficulty" level in the Security form to a high value, OK'ing the dialog box and then returning to the Security form, the set value is not kept. Neither it is saved when saving the database and exiting the program. Slider always reverts back to about 1/3 strength.
Running on WIN7 SP1 32 bit.

    Well, it is kept at the 1/3 mark after saving, closing and reopening the database. If you slide it back all the way to the left, you will see that it stays there too.

    More of a scaling problem than anything else. You may notice that the time to save and open the database is different on both ends of the scale. This is the best proof that the setting has an effect.

    Before I posted I did check the timing between slider at 0 and at 31 (max), and did not see much difference, hence my posting. Following your comment, I revisited and timed it: with slider at 0, on my system it takes about 1 sec to open the db, and when set to max it takes about 3 seconds. I would have expected at least an order of magnitude effort difference with the PBKDF between these two extremes. However, fixing the scale and making it X10 work factor or more at max is nice to have but no more than that. Thanks.

    I've increased the max value by a factor of four. On my machine, this gave roughly 12 second at the max value, which should suffice.
    Commit e493666, will be in next release.
