SYMPTOMS
Activation of Kana keys in an MS-DOS box should affect system-wide Kana key
activation. However, 32-bit applicatons are not notified of the Kana key
activation.
CAUSE
The Input Method Manager (IMM) updates the KANA key status by using
SetKeyboardState() in the System VM. However User.exe maintains the status
for each 32-bit process, so the Input Method Manager KANA status is never
reflected into other 32-bit processes. This does not affect 16-bit
processes because the keyboard status is shared with all 16-bit processes.
RESOLUTION
Developers cannot maintain the KANA key status within applications. End
users need to be aware this behavior.
STATUS
Microsoft has confirmed this to be a bug in the Microsoft products listed
at the beginning of this article. We are researching this problem and will
post new information here in the Microsoft Knowledge Base as it becomes
available.
