Other changes:

Object/Enumeration	Property/Method/Constant	What has happened?	Comment
ImageViewer	WindowHandle	The type of the property has been changed.	The property has the __int64 type. This change has been made for 64-bit operating systems support.
IImageViewerEvents	OnActivePageChanging	Event invocation has been changed.	The process is not invoked if the active page is changed via API of Image Viewer. When the page is changed via API, the code developer is aware of it beforehand and does not need the notification. This process is invoked only when changed by user of the application.

	OnRecognizePage	Renamed	The new name of the method is OnReadPage.
	OnDraw	Removed	This method worked with low level drawing tools and presumed a large number of code to be written. As Image Viewer provides a wide variety of special tools for working with an image, so the method has been removed.
	OnTableCellsSelected	The second parameter has been renamed.	The new name of the second parameter is Rect. This name for rectangle input parameter is generally used in FineReader Engine API.

When the page is changed via API, the code developer is aware of it beforehand and does not need the notification. This process is invoked only when changed by user of the application.
	OnLocked	Event invocation has been changed.	The method is called after Document Viewer has been locked or unlocked.
	OnDraw	Removed	This method worked with low level drawing tools and presumed a large number of code to be written. As Document Viewer provides a wide variety of special tools for working with pages in the document, so the method has been removed.

When the page is changed via API, the code developer is aware of it beforehand and does not need the notification. This process is invoked only when changed by user of the application.
