Hi Charles, You may have some data in the clipboard. Open any text file, then select one character and "COPY" it. That should reduce the clipboard (copy buffer) size to one byte.
Also, what parameters did you give the CLEAR command? Just "CLEAR" by itself probably won't do anything. You probably need something like "CLEAR 0". Hope that helps.
