Security through RSI
This is the most irritating dialog in Windows. Why on earth do I need to type my WEP password twice? It's a huge hexadecimal number. Is it a security feature? Are hackers really breaking into my Router by randomly typing in huge keys and are therefore deterred by having to do it twice? What other system requires you to type a password twice to gain access (rather than to, for example, confirm a password change)?
