Mariano Gomez takes on what we hope is a pretty rare occurrence. A user was locked out of GP because someone was clearing data. Actually, the clear data process had hung up locking out all users. Mariano describes all the details and the fix. I would hate to see an error message that says “Someone is clearing company files and you cannot get into this company.” That will give me nightmares for a week.
