In both Mozilla-Mac/2004042110 and Thunderbird-Mac/0.6, the blinking text cursor leaves detritus during a scroll operation by arrow cursor key. Note that this does not occur in HTML TEXTAREAs on web pages. Reproducibility: Always. Steps to reproduce: 1. Start a new message 2. Type "foo" and a linefeed; repeat until a vertical scrollbar is shown 3. Use the up arrow to move back up the page until the pane must scroll. Expected results: Scrolling without detritus generation. Actual results: Detritus left behind by the clinking text cursor.
