Have a file that was converted from 9 to version 10, when I open the file, it opens but when I try to use the menu buttons to go to different functions,i.e. File, Edit, View, etc.) the program locks up with a program not responding and it forces me to have to close the program. Had no problems until I convered from 10.0.1 to the version 10.5.1 update. Any ideas?
