Using latest WF8 build from sources.
On Web-Console when trying to add a new log category, the dialog window
opens, but the Name field is locked. Indicated by a small padlock right
to the field.
Only "Log Level" and "Use Parent Handlers" are changeable.
Since I update WF regularly and also use this dialog regularly the
problem cannot be there for a long time.
It all time worked for me in the past.
