Just updated from v3.13.1600 to 3.15.1643 and noticed that under Tools > Startup, pressing the tabs to sort the keys (Enabled, Key, Program, etc.) that they don't retain that same order once CCleaner is closed.
For example, I always kept it alpha order and with Enabled entries listed on top. With the 3.13.1600, it remembered this view whereas newer versions kept resetting after exiting the program.
