Hey guys I've been using ABrosia for years now and I have never seen this before. I did not get a screen shot but when I try to backspace and change my settings I get a boxed zero for whatever reason. I have to restart the whole Neocodex manager before I can actually replace my settings. Does anyone else get this problem? Did I do something to my keyboard settings? I haven't had this problem with any other program on my computer.
