The software is from 1997 so it's a bit old - not that the language has changed much though. It doesn't run full screen, though. I still use it as it teaches the Thai language in a very simple way - from learning the letters and their sounds to reading, writing and listening a large set of phrases. The 'inter-active learning' is not related to auto-correction but related to comparing the given answers to the data-base answers. If you're interested, send me a PM.
