Reversion to 1.3 and this behaviour went away. Have not tried with smooth scroll off in 1.4a. Reproducible: Always Steps to Reproduce: 1. Select a long piece of mail. 2. Use the space bar to try to see more. 3. Actual Results: voila, message skipped, now looking at next message. Expected Results: scrolled down, stopping when hitting the end of the message as 1.3 does.
