(PASSWORD LOCK YOUR SCREEN/PHONE)

Here's how to do it:

Go to Start >Settings >Password or Lock (non-touch screen smartphones: Start >Settings >Security >Device Lock).
Select the check box labeled “Prompt if device unused for.” In the corresponding drop-down box you can specify any time from 0 minutes up to 24 hours. This specifies the amount of time, after your device powers down, before password protection is activated.
In the “Password type” field, select one of two options:
Simple 4-digit: This lets you enter a simple 4-number password, which is easy to enter, but susceptible to brute-force solving by a potential hacker.
Strong Alphanumeric: This lets you enter a longer password. It must be at least seven characters, but can be as long as 20 characters and must be a combination of letters (upper and lower case), numbers, and symbols. This type of password is harder to remember and enter, but is much more resistant to being cracked.

Once you’ve entered your password and confirmed it, tap OK (or Done) and you’ll be asked if you want to “...save password settings changes?” Tap Yes (smartphones: Done).
If you leave your device inactive for the period of time you specified in step 2 above, it will lock up. To access it, you will have to enter the password. If you think you’ll have a problem remembering it, write it down and keep it somewhere safe, but not on your device! If you do lose your password, you’ll have to hard reset your device.
Note: The time you set for password protection begins being counted after your device powers down. For example, if you set your device to power down after 3 minutes of lack of use, and you set the password time for 5 minutes, password protection is activated 8 minutes after the last time you use your device. If you press the Off button on your touch screen device, password protection is activated after 5 minutes.

This is great if you want to lock the screen. Now I've decided I don't want to any longer, but I cannot unselect the "Prompt if unused for" checkbox. Can you help?
