It's almost entirely compatible, but I apologize for the breakage you experienced. The reasons it was replaced it were that it (a) has a better libdialog API, (b) has a better license (LGPL instead of GPL), (c) is maintained, and (d) supports 8-bit character sets. If there is some specific feature you are interested in (--hline for instance), I'd suggest writing to Thomas Dickey, the maintainer. -Nathan
