Error: Formula field is being held

[Customer Service]

Harmless internal error: "Formula field is being held: <x>,
Count = <y>" in drill down from report Preview window.

Resolution/Workaround
In some cases an internal error, "Formula field is being held:
<name of field in report>, count =
<number of times user attempted drill down>" is
reported when you close a report Preview window after drilling
down to another report. This is a harmless error returned by
the Crystal Report Writer. The problem has been reported to
Seagate (Crystal Reports' manufacturer).

This is a harmless message that you should ignore.
