Thanks, will do in a minute - struggling through patients/paper work.

Another consideration is this.

At the moment the magnification is magnifying from the loaded image which has 
been shrunk to fit the drawing area.

One really needs a copy of the image, not shown on the screen which would 
hence be the original image size. The co-ordinates of the mouse, should be 
taken from the 'shrunken image', but the data for the magnified area needs to 
be taken from the 'hidden' image, ie the image in memory.

Regards

Richard
