Hi there,
I've notice when I've been navigating in closed runs that the breadcrumb navigation for sections doesn't work. It returns me to the all projects dashboard with a red error message "Field Section is not a valid section." It's been very helpful having breadcrumb navigation from test case level and I've been using it a lot in active runs but only recently in closed runs so hadn't picked up the error consistently.
I've got a local server install of TestRail and am using Chrome Version 29.0.1547.66.
Thanks,
Bethani
