I've discovered (over the years) that two things are prevelant: My inability to remember PM's as they were written and my computer's inablilaty to remember (with the "back" button)... which might be the fault of either "keyboard/monitor interface error" or "the gremlins ate my homework error"... but, either (pronounced eye-ther) way, I *almost always select/copy my PM's as to not have to retype... unless, of course, I'm improvising, and then a combination of chaos and kharma must override a sense of decency.
