 If the Edit > Links choice is unavailable, the link is permanently
broken and your object has become a picture. It can't update from the
source. Re-create the object.
 In the Links dialog box, if the file is set to Manual Update, click
Update Now, and the file should update.
 In the Links dialog box, if the entry for the file says Unavail, the
source file is not where the application expects to find it. Use Change
Source to locate the file and re-establish a path for the link.
ODBC Problems
Missing ODBC Trace
If no values are found for one of the selected columns in a query, the trace
will not be drawn and the value in the legend reads No Data.
If the necessary time value is not defined in the query, either by a date/time
column or by a placeholder tag, the trace is drawn as a straight line using
one value.
Missing ODBC Data Sources
Occasionally, an ODBC data source cannot be found. This can occur
because the data source was deleted or because the ProcessBook .piw file
has been moved to a machine that does not have the same data source
defined.
