The window layout looks like
|              Title       |
|  primary  |  help  |
|            license     |
|            exit          |

And on every valid keystroke primary and help need to be refreshed.
ncurses is optimized to handle this correctly.
However the wborder command on "primary" and "help" for some reason
touches "title" and "license" as well - so the doupdate() ncurses
functions refreshes them as well.

If you could find a way to solve the problem please let know - a patch
would be better :-)

No problem - segfaults should be fixed :-)


Again - thanks for your comments: I'd like to get this program into
tip-top shape so when I get the bsd.port.mk patch I'll just submit a
PR and wait for the flames :-)
