fara2000,
Sergey can confirm, but as I recall when you insert a picture (RichViewEdit.InsertPicture) the graphic is then "owned" by the richview and you no longer have to free it, the richview will do that for you. Just comment out the Bitmap.free call.

Yes, it's correct.
Do not free the image after calling InsertPicture or AddPicture
