Cause: In the SF the "Allow navigation" rights checkbox is disabled for the subject.
The Web GUI disables navigation between rows overall based on "Allow Navigator". The Windows GUI only uses this setting to disable navigation buttons of form and ribbon.
There is an extended property available for the Windows GUI to copy the behaviour of the Web GUI:
useallownavigationasrights = yes
Due to technical difficulties the Web GUI doesn't met the Windows behaviour (yet).
