KIS000301 - Unintentional application switch to background when key blocking is disabled

Unintentional application switch to background when key blocking is disabled		KIS000301
Overview	After disabling the key blocking with CAknAppUi::SetKeyBlockMode(), certain key combinations cause the application to switch to background unintentionally.
Reported against	S60 2nd Edition, FP2, Nokia 6630, Nokia 6680 S60 2nd Edition, FP3, N70, N90
Date identified	November 10, 2005
Symptoms	-
Detailed description	Most S60 games set the key-blocking mode off to allow multiple simultaneous key presses. This can be done in the application UI (CAknAppUi) implementation by calling SetKeyBlockMode(ENoKeyBlock); On S60 2nd Ed, FP2 or newer devices, the following combinations of keys pressed simultaneously are known to cause the application to switch to background when in non-blocking mode: ’7’ + ’8’ + ’0’ + ’*’ ’9’ + ’0’ + ’#’
How to reproduce	(See detailed description)
Solution	No solution exists. Key mapping in games should be designed so that the player does not accidentally press the above combinations.
