Understanding computer analysis

I'm totally new to this site. I played a couple games against the computer and requested a game analysis afterward. When I click on blunder (or error/inconsistency), I see the board but I can't interpret what it's showing me. Specifically, it shows my pawn in a green square with a green square diagonally behind (is that my move with my pawn ending up in front?). It also shows my bishop with a green arrow two diagonal spaces to the left into an opposing pawn square (is that the recommended move?) and it shows a blue arrow from the opponent rook clear across to my side of the board where my rook sits (I don't understand what this is showing). Help? Thanks!
Blunders are serious errors which will win the game for your opponent if your opponent finds the correct responses. I recommend you to pay close attention to your blunders and try avoiding making them in the future. The computer analysis shows your opponent's last move, the move that you have just made and the move you should have made.
Regarding mistakes and inaccuracies, it is less clear. Sometimes the computer analysis is wrong. It has never been wrong with blunders though.
Yeh I agree. Sometimes the computer points out things that are not wrong and actually good moves by humans point of view such as a move that was actually winning by +15 instead of another move that was winning by +20. No human difference there but still an "inaccuracy." Rarely but sometimes an inaccuracy will be pointed out by the computer that it doesn't like but since humans can perceive strategy it was a good move. Such as the first few moves of an opening or exchanging a bishop for a knight in return for doubled pawns. Things such as this the computer sees as black and white but humans can perceive long term plans where a computer just calculates its "fastest" way to mate or gain materials.

noob2chess--I do see my two games. I'm not sure how to link you to them.

Was I right in my OP about the direction of the move?
how to add a link to a position:

just enter analysis mode of that game, navigate to the position in question (this changes your address bar, it adds '#<movenumber> to it'), then copy paste the complete contents of your browser address bar into the post. This will be automatically transformed to a link.
#5 I agree, almost always the computer points out things which don't matter (and omits things which do matter) to a person.

Honestly what matters is how large your advantage (or disadvantage) is, not CP loss. Losing 100 CP when you're already up a queen doesn't matter; losing 100 CP in an otherwise drawn position is huge.
