In 10.01.2002 (german date format dd.mm.yyyy) I mentioned, that very
often delphi hangs up, when I close some of my projects, that use IBO.
But in the discussion-thread we found no solution for the problem,
because it's not reproducable.
Now I have done some further tests and it seems, that the
Property-Editor of the IB_Query causes the problem.

1) I open my project and change the prepared-property in the
object-inspector of any Query to true. Then close all and all is fine.
2) I open my project and open the property-editor of any query by
double-clicking it. Then I try to prepare the query with the
toolbar-button and get an access violation. Then I close the
property-editor and close all and Delphi hangs up.
3) I open my project and change the prepared-property in the
object-inspector of any Query to true. Then I open the property-editor
of the query, but the query is unprepared (is this the wanted behaviour
? ). Then I try to prepare the query with the toolbar-button and get an
access violation. Then I close the property-editor and close all and
Delphi hangs up.

The main problem is, that this behaviour depends on the project. At some
of my project all works fine and at the others I get the error. But at
the projects I get the error, I get it all the time, that means there it
is reproducable.

I have never coded a proprty-editor, therefore I don't know, where I
should search for the problem, perhaps some of you have an idea ?

I'm using W2K SP2, Delphi 5 Enterprise, IBO 4.2 Gc
