Hi,

This was reported 9 years ago, but unfortunately never got a reply at
the time.

Are you still seeing any of the below issues with a modern version of
Emacs?  A lot of things has changed over the years, and it would be
good to hear the current status.

Best regards,
Stefan Kangas

> 6. Problem #2: Selecting "a" and clicking on "Watch expression" opens the Speedbar but does not display the value of "a", as it does with Aquamacs 1.9 (with Aquamacs 1.9, the behaviour is still not perfect, as the values of variables are not displayed dynamically in the Speedbar as they change, in contrast to what happens when Emacs is run on some Linux platforms).
