Q: 	Optical mice use an LED and a camera to rapidly
capture images of the surface beneath the mouse.
The infomation from the camera is analyzed by a
DSP (Digital Signal Processor) and used to detect
imperfections in the underlying surface and
determine motion. Some materials, such as glass,
mirrors or other very shiny, uniform surfaces
interfere with the ability of the DSP to
accurately analyze the surface beneath the mouse.
\nSince glass is transparent and very uniform, the
mouse is unable to pick up enough imperfections in
the underlying surface to determine motion.
Mirrored surfaces are also a problem, since they
constantly reflect back the same image, causing
the DSP not to recognize motion properly. When the
system is unable to see surface changes associated
with movement, the mouse will not work properly.
A: 4

He is staunchly against gay and lesbian rights, which as they are americans should be affored the same rights and roles as everyone else.\n8. He flaunts his power, even though he doesn't have a clue on how to use it.  His IQ is one of the lowest of any president in history; he hasn't written any of his own speeches, let alone a book about his policy and life.

He has put our boarders at risk, even from the canadians.\n11. He has severed ties to some of our oldest allies, simply because some of our allies think that he has gone to far in his push for world peace.\n12. He is constantly trying to push his world agenda onto other conountries, and forcing democracy into their countries without their consent.\n13.

He doesn't aggree with the Geneva Convention, in fact he has wanted to rewrite it several times.\n16. He wants to actually remove us from our seat at the UN, which would be catastrophic to the agency as we hold a founding seat.\n17. He has invaded Iraq under false pretenses, and continously defends our rights there; whereas we should have no rights there as that is NOT our country or our protectorate, instead it is the soverign right of the iraqi people, not americans.\n18. He neglects his duty as president and spends more than 1/2 his normal time and term on vacation or away from the white house.\n19.
