We are currently experiencing an intermittent issue effecting 2 people whereby a user is working in Word and it will lose focus. To restore focus, Shift Tab to different application then back to word, or minimising and back to word both work.

Both users have word 2010 installed on windows XP.

The occurance of the issue has varied from multiple times a day to once a week. The first occurance of the issue happened on 26/11/2013.

We have seen the KB313176 and the suggestion to resolving the issue is to turn off advanced text services, this has been turned off on one of the machines and the issue has still occured.

Would you please be able to advise on what may be causing the issue.

Thanks in advance

Regards
Danny
