Still an issue in 13.11 😮💨
UPDATE: For anyone who finds this in the future. I tried restarting, cleaning media, and rerunning the latest update installer to attempt to fix the issue, however, none of that worked. I was able to fix the issue though. Launchbox is installed on a NAS, so I tested opening the options menu for the same install on a different machine. The second machine could open the menu, change a setting, and save. After doing so, I went back to the first machine and it was then able to open the options menu without issue. I'm not sure what would be system-dependent about this issue but hopefully, this is a helpful piece of the puzzle to someone.
