Ok, I was wondering if you could explain this.
The following code works on some images and doesn't on others. The ones it does not work on it will crop right on the second try, but the first crop you attempt is always wrong. Any ideas?

Code is as follows....

void __fastcall TForm1::ImageScrollBox1QuickSelect(
const TImageScrollBox *Sender, const DibGraphic *Graphic, const TRect &Rect){

TCropTransform *transForm = new TCropTransform;
transForm->CropMode = cmExtractRect;
transForm->Top = Rect.Top;
transForm->Bottom = Rect.Bottom;
transForm->Left = Rect.Left;
transForm->Right = Rect.Right;
delete transForm;

Thanks for your time.
