Problems with console short cuts (sequences)

I tried to set up hardware monitoring. Therefore I entered the console and tried to enter "Hardware configuration" (C-A-W. But every key combination returns to the "begin screen" (the screen with Welcome to Data Storage Software V6).

It looks like every key combination with the left alt-key, with or without control-key, closes the menu. The f2 and f5 options also do no "work".

Does anyone know how I can resolve this problem? (No key sequence seems to go to its funcionality).
