Keylock/Keyguard stopped working?

[beckkl]

My wife's treo pro all of a sudden lost its keyguard. It is enabled in Settings, but when she presses the home/red button, nothing happens. But the button works fine. Its like it is turned off, but I swear, its enabled. I did a soft resent, changed the keyguard timing settings, etc. Nothing. Has anyone else seen this? My last resort is a backup and reset, but I was hoping maybe i can tweak the registry to fix something that somehow got changed.

Any thoughts would be awesome.
