Hi,
Update on the CUI HotKey functionality:
If Hot Key is enabled, it does CUI operation - for e.g. "Screen Orientation". It is a system wide behavior regardless of the application user is currently in. Also, when the Hotkeys are disabled, it cannot be released for use in another application as we cannot register the same keys back.
Resolution / Workaround:
1. When a user wants to use a particular hotkey combination, for example "Ctrl+Alt+UpArrow", rename the key to any other key combination e.g. "Ctrl+Alt+U". Now the "Ctrl+Alt+UpArrow" will get unregistered and will be released to be used in any user applications. 2. Other option is to kill the Hotkey manager process (igfxHK.exe) from task manger. This will release the keys that can in turn be used in users application.
Let me know if this helps.
