Hi!
  evalign seems to have some type of sensor error.  I loaded 
a mask, and reached the adjust mask step.  At that point, the 
aligner began moving the eyepieces on it's own.  It quickly 
reached the endpoints.  I tried to exit, and the machine 
seemed to lock up, but when I jiggled the joystick, it would
proceed another half step.  I successfully unloaded the
mask, and informed the next user.  He said he's going to
give it a try, and shut the machine down if he fails.
Thanks!
Mark
