I still use Lockscreen in some places, it still happens that is is necessary.

However I advice to make use of the memento pattern which will solve a lot of your trouble and makes your code much more generic. Since I started implementing this I found many other situations where this technique can be used and makes your life easier.

Create a class which stores the initial setting in Init and restores the setting in Destroy().

Then you can instantiate the class and when the object gets released it reset's the state to it's original value.

LOCAL loLockscreen AS LockscreenState OF Utils_State
loLockscreen = NEWOBJECT("LockscreenState","Utils_State","",THISFORM)
THISFORM.Lockscreen = .T.

Anytime when you need to reset lockscreen, you release the object:

RELEASE loLockscreen

Or at the end of the method it releases automatically.
