There is soooo much code in all of these things....

Anyhow, the good news is that I have found the problem. Here is the
offending code in OnCalculate event:

if AField.FieldName = 'ENCOUNTER' then
with ARow do
if ByName('ENC_START_DATE').IsNull then
ByName('ENCOUNTER').Clear
else
{line 6}qryPatMorb.Fields.ByName('ENCOUNTER').AsString := format('%-10s
%-40s',
[FormatDateTime('ddddd t', ByName('ENC_START_DATE').Value),
ByName('ENC_PROVIDER_DESC').Value]);

The problem is that when converting from IBOQuery I had to change references
to ARow instead of referencing the query directly. Well, I missed one
reference on line 6. I guess that reference was changing the cursor position
or something.

Thanks for your interest.
