Just a thought... most problems with scripts acting differently when executed out of crontab are related to the restricted environment that is set up by cron for the programs to execute in. Perhaps the version of "ps" invoked by cron is different from the version of "ps" invoked when you run it on the command line.

It might be valuable to run "env" in the script and store its output in a file, for later examination. You "should" see that PATH is probably different from the path you have in your command line shell. There may be other surprises when comparing them with the environmental variables present in your command-line environment.

The 78 character width is sneakily suspicious to standard tty width.
Why are you so confident it is not the ps command?
My hypothesis of the problem would be the ps command cannot identify the output terminal and so it is defaulting to the default tty settings.

In your script, try experimenting also with the 'tty' command. This will either correct your problem or give you better insight.
Thanks for the suggestions, I'll have a play around this weekend.
