Solution 

This rare issue is caused by Windows refreshing the GUI (say after merging some documents and Word comes up) and in the process, not re-rendering it correctly.

1. On the affected machine close LawMaster and Outlook NOTE: This process is best carried out by your IT people. 
2. Go to C:\Program Files (x86)\LawMaster\Client\PracticeManagement\Versions\
