Two builds ago - I stopped using the WM 6.5 lock screen because TF3D would pop up over the lock screen. Anyone else having this issue?

Lock your phone, put it in standby. Wake it back up. Count three seconds. It will look like it automatically unlocked because TF3D will be responsive... but try pressing Start, or the soft keys, or anything like that - they won't respond because the phone is still locked. You have to put it into standby, wake it up, and unlock it before TF3D shows up over the lock screen.

Any way to stop this?

There's a difference between crackberries and the Touch Pro. Sure, you may be tweaking and working on the TP every day - people with blackberries spend time USING them instead of tweaking/reflashing/repairing them
