I just downloaded the demo, so I am most definitely a newbie, but this just weird. When I open a text file that is already existing, the text initially displays just fine, but when I try to edit it, all but a few hundred characters at the end of the file disappears. At that point, as I type new characters, characters from the beginning of what is displayed begin to disappear. One character gone for each character added. I tried to save the file to see if the info was really gone for good, but the demo won't let me. I also tried creating a file from scratch and, sure enough, when I get several lines into it, all of a sudden the initial text disappears. Any clue what's going on?
