I just did a number of diffs with no crashes. I tool a break for a few seconds to talk to someone, pressed a single character and SE crashed. This time I got the usual dialogs but did she the Slick-C window but could not copy the contents or select it. This time I got several "Invalid argument" dialogs and only one of the "This property or method is not allowed on this object" dialogs. I've attached my logs. Not sure the diff macro change will help here since SE crashed while NOT running the diff. I can open a different topic to track this if it helps. Not sure they are related--same dialogs, but they are so generic it might not be the same type of error.
