However, Informix does not use standard Curses libraries, and it is not part of the Informix Curses library, so it cannot be used sensibly. Why doesn't Informix uses standard Curses libraries? Because when our products were first produced, the curses implementations available were flaky and inconsistent, and it was better to use a known, not-so-flaky version that we could guarantee than to try using the system version with unknown defects. To some extent, that still applies, but not so clearly. We also need to ensure that we had 8-bit transparency and the ability to handle colour.
