I am evaluating TRichView for general use in my applications (using Delphi

7). I am using default properties. When I use only text, everything works

fine (printing, copying to file and clipboard, etc.). However, I have tried

inserting a graphic with AddPictureEX as per the code snippet below. The

graphic is being copied as a bitmap from a portion of one of my open forms.

miniBitmap:=TBitmap.Create;

miniBitmap.Width:=sourceWidth;

miniBitmap.Height:=sourceHeight;

ImageForm.ClipImage2.Picture.Graphic:=miniBitmap;

ImageForm.ClipImage2.Canvas.CopyRect(Rect(0,0,sourceWidth,sourceHeight),Canv

as,

Rect(sourceLeft,sourceTop,sourceLeft+sourceWidth,sourceTop+sourceHeight));

miniBitmap.Free;

AddPictureEx('',ImageForm.ClipImage2.picture.graphic,0,rvvaBaseline);

At first, everything seems to work fine. The graphic appears, can be

printed, etc., but when I close the application, I get a Delphi memory

error crash. The error does not occur when I close the form(s), but just

when I close the application. This same procedure is succesful if I do not

use TRichView but instead just copy the graphic directly to printer, file or

clipboard.

What am I doing wrong?
