Guido,
I have to say I don't know, but I doubt there is any difference. I've just
simply never had this problem with *any* version of a Delphi or IBO
design-time package. I use both indiscriminately without mishaps. Both
the Object Inspector and the property editor correctly report the Prepared
status of a statement.

Is your creation order OK? Is is possible you have any data objects
with dependencies on objects that are not created until run-time? e.g. a
form that is created before a data module?

A silly question, are you trying to prepare a statement which has no
SQL? Sometimes we just overlook the *most* obvious things. What does the
monitor tell you, in those conditions where you are actually able to
initiate a Prepare?
