Will somebody please explain to me what the bloody hell those little boxes of upper and lower case letters and numbers ,for security ,or something are all about ,cos i havent a bloody clue.They're all distorted and jumbled up together ,sometimes with coloured patterns behind them and you have to dechipher the 'items or write a strange word. I was having to write 6 letters n' numbers from a box to send a mail, but for the life of me i could only find 5. What and why are they there for. You have to write the letters from a stupid word which is often quite easy, but then theres coloured ones and then it becomes an optical illusion which can make you dizzy and feel like your 've been smoking some weird substances, which actually would be better as that would make me mellow rather than drive me into that pit of driving rage and frustration as the red mist decends as i keep getting knocked back by the bloody computer for some distorted grammatical mistake in trying to dechipher the distorted grammatical and numerical mish mash in the first place. The stuff on the computer may be safe ,but i become very unsafe ,infact downright dangerous.
