Hummmm
what you running it on? console or xterm or rvt or gnometerm?
I can see silliness on a console but that is really down to a duff termcap

see if you export TERM=vt100 it's fine (admittidly in black and white,..)

Now I'm unsure which file it's reading for the info /etc/termcap or
/usr/share/terminfo
One is from the termcap package and the otehr from ncurses. I'm going to make a
stab at termcap being the guilty party


Over to you Bero 8)

We assume, you mean with 'console' a replacement for a real 
system-console (Alt F1 or Ctrl Alt F1) == non graphic mode


We have tested your scenario on FEDORA CORE 4.
We have tried to launch (on 'console') (default settings):

/usr/share/doc/dialog*/samples/yesno

yesno  (yes-no-example-dialog) works, but some semigraphic 
        characters are not correctly displayed, keys are 
        correctly interpreted.

If we launch (on command prompt):


     setfont default8x16


Now, 'yesno' works fine, alle semigraphic characters are
correctly interpreted/displayed, keys are correctly interpreted.

NOTE: The 'box' (== semigraphic characters == ACS_HLINE, ACS_VLINE,...)
      are displayed only, if the current font 'supports' this 
      characters.
