I'm not positive here since I haven't done any testing, but based on how I've seen the updates work and general things I've heard, I will draw a conclusion (possibly incorrect) that might help you... When GameEx installs a new version, it creates a backup of you GameEx.ini. When it installs, it creates a new GameEx.ini from the installer. So, I'm guessing that it then goes through your ini file and grabs the settings that you have and puts them in the new file. The only other alternative is that it will grab the new settings from the downloaded file and put them at the end of your old ini file. BUT, if it did that, then you wouldn't have any significant changes in your ini (which is not the case). As such, I suspect the former is true. If that's the case, then the answer would be that GameEx doesn't support user comments in the GameEx.ini file. That might not make sense (after reading it, I'm not sure I understand it). Anyway, maybe Tom can explain the real answer.
