Delphi3 vs Oracle73 - TDBMemo or BDE Caching problem

Hi there!

I try to develop a press editors application using Delphi 3 CS and
Oracle 7.3.2. This application consists of more than a hundred forms and
raports. So to avoid consuming a lot of MS Windows resources all forms
are created dynamicaly. But sometmes (!!!) during form creation I
receive Access Violation error during Form.OnCreate event. Form creation
events works good and stable when TDBMemo components are disconnected or
TBDEDataSet.CacheBlobs := FALSE. All memo fields type are of

Can someone help me? How to solve or workaround this problem which
appears without any found definition (appears frequently when one form
creates new one)???
