Pattern lock screen sometimes not centered?

view story

http://forum.xda-developers.com – Sometimes when I use the power button to unlock the screen saver, the pattern lock screen is off center. It's so far off center I can't enter the pattern to unlock the phone. I have to press the power button twice to get a new pattern lock screen that is centered. I was wondering if anyone else has noticed this with their phone. I've got Executive Assistant running under the lock screen. (HowTos)
