I'm afraid it is true there is a bug in RASTOP concerning one wide moves. The more complete picture is that when the source is to the LEFT of the destination, rastop tranfers (width - 1) columns instead of (width) columns. A side effect of this bug is that when the width specified is 1, the column counter counts through 16 bits worth of columns, crashing the terminal when it touches illegal memory. The problem has been fixed here at BBN, and will be available with the next software release. Rich
