Thanks @Eric : it does indeed work nicely -only not in the sidebar; after
the streamlining you've done on Charlie's script, that functionality seems
to have been compromised.
@Hans: Have you implemented Eric's script without modification, and does it
display & function correctly in your sidebar?
Anyway: Without really understanding the code, i'm now using Eric's macro
definition line at the top, followed by Charlie's UI-related code, and that
seems to work pretty well, tho the sidebar view doesn't flow so well if
it's set too narrow; i can certainly live w/ this -happy! /w
