I just found a couple nasty bugs that I have no fix for yet, but do have work arounds for.

Some of the widgets and buttons might stop responding to taps. I think there is a bug in the code that prevents the widgets from being accidentally tapped twice causing the action to be undone by executing it twice. If this happens just open the process viewer and kill ASUI. This probably exists in the release version as well.

If the ambient light sensor on the n810 causes the theme to change while the secure keypad is visible it triggers a bug making the keypad jump around the screen and you won't be able to enter your code. Just open and close the clock or flashlight and the keypad will work fine again.

I don't normally run ASUI and systemui together, only for testing purposes but I'll test it out soon. (that is the bug you are refering to right?)

Not sure if I missed it but did you test the sequence between systemui and mce when locking the device?
