Found a fix for this problem. Following is from the MicroSoft website:
In detail, open the Control Panel,
if you're using Windows XP, double click the 'Accessibility Options' item.
In the Accessibility Options window, switch to the 'Keyboard' tab and
select the checkbox before the 'Use FilterKeys' option;
if you're using Windows Vista, double click the 'Ease of Access Center'
item and then click the 'Make the keyboard easier to use' link. In the
window opened, select the checkbox before the 'Turn on Filter Keys' option.
You will also need to select Filter options, click on settings, and select No Keyboard Repeat.
