The Scroll Bar was intermittently getting disabled and dimmed.
This happened when any data was sent to the screen causing the scroll bar to move while MacWise was in the background. The symptom commomly occured when MacWise was in the background and the host timed out the telnet session, sending the "connection closed by foreign host" message and causing the scroll bar to move.
