Thanks for the suggestion but, no, that was not the cause of the problem.
This is a problem that is going to prove very difficult to track and reproduce. I know it is happening and I know it is not due to human error (i.e. I am not deleting any lines, etc.)
The only thing I am able to do is to do daily backups and constant workspace savings but knowing that this problem can strike at any moment is not a very pleasant solution for the user.
I am surprised nobody else is having or reporting this issue.
Thanks for now,
Stopped
