Unable to disable Caps Lock in Outlook Express

Why I could not set my Caps Lock off while I am typing in Outlook Express? How to overcome?

This is because you’ve accidentally pressed ‘Shift’ key more than 5 times then ‘Shift’ + ‘Ctrl’ + ‘Alt’ keys. So, all the capitals that you’ve typed will be in big capital even thought you have pressed ‘Caps Lock’.

To overcome this problem, press again 5 times of ‘Shift’ key.
Then, you will see ‘StickyKeys’ message prompt out.
Press ‘Shift’ + ‘Ctrl’ + ‘Alt’ key for 2 to3 seconds and release. Press ‘OK’ to close the Windows Message and try to type again.
