From the dashboard page, select log viewer, open log, close log, taken back to dashboard instead of log viewer.
Thanks for reporting this. I’ve opened the bug#3138.
To update to the modified package (after mirrors are synced) type:
yum --enablerepo=nethserver-testing update nethserver-base-2.7.1-1.3.gb8fa61e.ns6
Returns to the log list after ‘closing’ an open log instead of to the last module viewed, looks great!
