Hi.
I seem to remember that this was reported before, and that a fix was supplied but I cannot find it in the Forums.
The Navigation breadcrumbs are truncated when L4Mac is first loaded. This happens regardless of whether the TOC is open or not.
The breadcrumbs can be reinstated by opening (or closing) the TOC side panel.

On a related point, when the breadcrumbs are displayed, they are 'shortened' at certain points dure to lack of space ... even when there is no lack of space! The screen shot below is the same as above but with the TOC closed. The Navigation breadcrumbs seem to have displayed themselves correctly but are not using the available space.

Regards
Martin.
