D7 & ADO with ASA9: EOLEException & Multiple-step error

Good day!
I'm using D7 with ADO, connecting to an ASA9 database.
I am converting the application from an older version using BDE.
I have a DateTimeStamp field in this particular table (among about 30 other fields, including dates). I retrieve a single record for display purposes. Ass goes well until...
At run-time, I can not access the DTStamp field data of the ADOQuery (should contain something like 2003-06-23 11:58:05.809) in Debug mode. If I rest my pointer over the ".AsString" part of AdoDataMod.aquGetClipReadOnly.FieldByName('DTStamp').AsString, I get the yellow ribbon hint with the text "Delphi Exception EoleException at $3E2F949". Same thing if I switch from ".AsString" to ".AsDateTime".
If I continue anyway (F8), I get a Message window titled "Debugger Exception Notification" with the message:
[Project IMC5.exe raised an exception class EoleException with message "Multiple-step operation generated errors. Check each status value"]
What is a multiple-step operation?
What status values should I check?
All the other fields (integers, varchars, dates, etc...) in the ADOQuery are fine.
I tried removing the fields from the ADO query, I tried adding them back in again, I tried closing everything (including the DB Service) and rebooting - so far so bad...
The BDE version has been working with identical data for nearly 10 years without a hitch - it still is.
I looked for references to this in the newsgroups and on various Web sites - did not find much.
Am I the only one with this problem?
Thanks for any info or pointers you may provide.
