Re: dialog problem with --programbox

[Gary Cowell]

That would give the output in one go at the end.

I'm trying to use --programbox to display the live output of a running
pipe (actually the progress log from a database export job).

I think whether or not you see any output at all depends on your
terminal emulator and whether or not it switches to alternate screen
when curses kicks in.  If you don't use the alternate screen (e.g.
turn it off in PuTTY)  then you do see the tail of the output, but
--programbox still should display an 'OK' prompt, if I'm reading the
docs right.

I'm going to try and implement my database job using --prgbox instead,
and call a script with the prgbox command.  It'd be much cleaner with
--programbox though.

Thanks for the suggestion
