• An issue related to the update installation process was identified which could lead to preferences (including keyboard shortcuts) being reset to defaults.
  
  Workaround: Settings are saved in a file called default.cet135.cmpref within the CET Documents\Preferences\64-bit folder. Create a copy of this file when your desired settings are in place. If you can recover an older version of this file, you may be able to restore your preferences! You can create a copy of this file when your desired settings are in place.
  
  Solution: A fix for this was released with 13.5 Patch 1 (December 19th, 2022), but the reset could occur while installing this Patch, therefore we recommended backing up the aforementioned default.cet135.cmpref file.
