  With use of PrepareReport and ShowPreparedReport it works now fine :
  
  I use
  
  <span style='font-family:Courier'>frxReport.PrepareReport;
  frxReport.ShowPreparedReport;
  ...
  frxReport.DesigneReport;
  ...
  frxReport.PrepareReport;
  frxReport.ShowPreparedReport;</span>
  
  instead of
  
  <span style='font-family:Courier'>frxReport.ShowReport;
  ...
  frxReport.DesigneReport;
  ...
  frxReport.ShowReport;</span>
  
  and i open/close manually datasource instead of let Fastreport made this itself.

  FastReport demo has two buttons: one with ShowReport, another with DesignReport. I don't see any hangs when pressing these buttons one after other.

  I think that in this demo, the report is reloaded when you click buttons.
  
  In my application, the user can see a first preview of a standard report and if he want, he can update it by clicking a button. But, modifications are applyed on this live report without reload.
  
  My report has also a complex data access with query and a lot of master/detail datasources.
  
  I can try to reproduce this with a lite sample... But at this moment, I go to my bed, it is 1:10 AM in France.

  No, it is not reloaded, look at demo sources.
  
  procedure TForm1.DesignBClick(Sender: TObject);
  begin
  frxReport1.DesignReport;
  end;
  
  procedure TForm1.PreviewBClick(Sender: TObject);
  begin
  frxReport1.ShowReport;
  end;
