not a slacker
I solve at work, too, but I'm really not wasting any time. I multi-task. I have days when I leave over 250 phone messages. As I enter the last digit of the phone number on the keypad, I also click on the "Try another cryptogram?" link. Usually, by the time someone has picked up the phone or voicemail begins, I have solved the cryptogram. Sometimes the voicemail kicks in before I'm finished if it's a tough cryptogram, so I have to solve while speaking into my headset. That probably shaves a little bit off my time. If a live person actually answers the phone, it can completely break my concentration, and I have to abort. Ergo, I'll probably never have a 100% solution rate for the month.
