I have Office 2003 Professional and all was working fine. I removed Vista 
Business Premium and installed Windows 7 Home Premium. Now in Word 2003, the 
mouse button to highlight text is not working. It works to select File, 
Tools, etc, but not to highlight text. Actually when you first open word, the 
mouse might work once or twice, even sometimes three times, to highlight 
text. Then it stops working. You have to close word, and reopen it, and away 
you go again. Then close and open and keep doing that etc. Other programmes 
seem fine and no problem.
I have reinstalled Office and also repaired office, still not resolved.

Problem solved. The problem was caused by Lenovo Password manager. Anyone 
else with similar problem go into Preferences in your Password Manager, and 
remove the check against the HotKey button. Reboot and all appears OK (So 
Far).
