cannot paste after close/open editor

[kostyan29]

Hello! I have a strange problem. I try to use TRichView with database (Delphi 10.3, Firebird). File saved in BLOB field.

step 1. I read stream from DB, and load file from stream (RichViewEdit1.LoadRVFFromStream(stream)). That's all OK. I copy something in Word or OpeOfficeWriter (text,tables, pictures, etc.) and try to paste it into editor. On first time, I CAN do it. Clipoard was pasted to editor, and I can save it (RichViewEdit1.SaveRVFToStream(stream,false)). Then, I close editor's form .

step 2. I open file from DB again. All what I inserted on previous step is saved and loaded. All OK. Now I try to copy and paste something else from Word again. But now I CAN NOT do it. I use "Ctrl+V", right click of mouse and "Paste" command... It doesn't matter which way I use - I can not paste from clipboard. Nevertheless, I can type text, work with tables pictures, I can save it, I can load other files. I can do all but copying/pasting.

step 3. I reload my program. And after reloading I can paste from clipboard. But I can do it until I close form with editor. After I can not paste.

I think, reason in closing form with editor and following creating new form. Maybe, something stops working.
P.S. Sorry for my English.

Problem is solved. It was my mistake. Form don't destroyed after close. I just had added following code

procedure TRichForm.FormClose(Sender: TObject; var Action: TCloseAction);
begin
Action:=cafree;
end;

and all will works fine. Sorry!
