Problem: 	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.

Explanation: The passage talks about optical mice or mouse throughout which is a part of computer system. Thus, it is correctly classified to "Computers & Internet" 

Problem: A direct result from anxiety disorder isn't usually death, but it can certainly feel like you could die at times. If left untreated it could snowball into other problems, I suppose. For instance, if your anxiety is preventing you from leaving the house, you could be missing out on excersize. Just a small example.\n\nThe best thing to do is seek therapy and find out what it is that is the trigger for you. It can be crippling, and nobody should have to live like that. \n\nFor a quick fix, Xanax or a Benzo drug is effective, but not good for long term use. Zoloft is excellent, and non-addictive. The drugs are pointless without counseling though as you need to address the cause so it doesn't return after you stop your medication. It will help you to talk to someone. \nIf you don't wish to use medication, this is an excellent book that can help you better understand what you are going through. http://www.amazon.com/gp/product/1572244135/qid=1135212967/sr=2-1/ref=pd_bbs_b_2_1/104-5484893-1187962?s=books&v=glance&n=283155\nAnother helpful link: http://www.npadnews.com/faqs.asp#4\n\nGood luck!
