We are using elog as a small database system, today we came across a 
problem where 2 people were editing the same record and the first one to 
submit his changes were overwritten when the second person submitted his.

Is there anyway to lock a logbook record when someone has pressed EDIT, 
maybe set a flag in the logbook entry so it has to be unlocked when its 
submitted by the originator or by an administrator.

Many Thanks
