Hi Rick,

On the TImageScrollBox is a TImage, so the cursor needs to be changed on the TImage itself. There is the FImage data member of TImageScrollBox but it is protected. One solution is to create a temporary class to access it. For example,

type
TProtectedScrollBox = class(TImageScrollBox);

TProtectedScrollBox(ImageScrollBox).FImage.Cursor := crArrow;

This will allow you to change the cursor.

Best regards,

Michel
