NOTICE
Caution: Data may be lost!
Deleting line 0 from the tool table will destroy the structure of
the table. As a result, locked tools might no longer be recognized
as locked and, consequently, the search for a replacement
tool will not work, either. The problem cannot be solved by
reinserting a line 0. The original tool table will be permanently
damaged!
Restore the tool table
Add a new line 0 to the defective tool table
Copy the defective tool table (e.g. toolcopy.t)
Delete the defective tool table (current tool.t)
Copy the copied tool table (toolcopy.t) as tool.t
Delete the copied tool table (toolcopy.t)
