I have developed a problem with the search box on the homepage of my Logos 4. Whenever I start to type in it the circular timer comes on (as if it is searching) then the programme shuts down. A message box says that Windows is searching for a solution to the problem, but it doesn't find one. I can navigate around the homepage and type in the Command Box, just not the Passage or Topic box on the homepage. Is this a problem with my Logos or with my Computer/Windows?
