design report as no modal

pele

I try to open designer as no modal window.

report.DesignReport(False,False);

First time, works fine. but second time (when designer window is still opened), I try to clear previous designed raport and load new this way, but I get a lot of acces violation errors.

begin

      Report.clear.;

      Report.LoadFromFile(plik);

      report.Designer.ReloadReport;

    end;

How to do it properly?
