Text is lost because the maximum edit log size has been exceeded.

Cause

This message appears at the beginning of a cmdtool(1) session after 100,000 characters have scrolled by. Clicking the top rectangle of the scrollbar might display this message. No data were lost, but the user cannot scroll back before this wraparound point.

Action

To increase the maximum size of the Command Tool log file, use cmdtool -M, specifying more than 100,000 bytes.
