When I installed version 45.0 I had the same issue - when unified folders are selected and then you click on the unified folder the software freezes up. I uninstalled and reverted back to the previous version - assuming 45.1 would have fixed this issue I tried again - when I unselect Unified Folders it seems to work normally - I need unified folders, so when I get time I will wind back again until this is resolved. Thanks, JR
