Small Items

To clear up any potential confusion . . .

On letting the next class in:

We should never leave students alone in the tech classrooms. If the
next teacher in your classroom has not arrived before you need to
leave, you have no choice but to lock that teacher out. Someone from
the office can always come down to let a teacher in, if needed.

On syncing the screen and the projector:

Once you've plugged in the video cable, you need to tell the computer
that you want it to send a picture to both the computer screen
("notebook") and the projector ("monitor"). To do that, right click
anywhere on the desktop, then choose Graphics Options --> Output To --
> Dual Display Clone --> Notebook+Monitor. Once you've done that
once, the computer will often automatically sync to the screen when
you plug it in, but if you ever get a black or blue screen from the
projector when you expect the laptop to be mirrored on the projector
screen, try changing the Graphics Options first.

All for now,
