Description: '
'
The BTV! stack trace command starts printing at the frame that is selected in the backtrace-stack menu.  This is most annoying, since you usually want the whole stack, and aren''t warned about the listing''s incompleteness.'

Actually as they say "That''s not a bug that''s a feature."  BT and its friends start at LASTPOS.  The backtrace menu sets LASTPOS to the selected frame.  This allows things like ?=, REVERT and ARGS to work on the selected frame.  I am pretty sure that is the desired action in most cases.  '
'
I will update the documentation BT and friends to point out that LASTPOS can be set by selecting the display backtrace.  '
