I have to kill -9 the 'pine' user process to free the shell. After this
is done, immediately executing 'pine' works. The problem consistantly
occurs under a VT and under an xterm.
Perhaps this might have something to do with the what I reported earlier
(but didn't seem to generate any discussion or response) with the LINES
and COLUMNS variables in a newly started 'bash' shell not reflecting
their true window dimensions.
