Distortion of Shape while Moving it on a Panned Area

Question

Hello          I have an application in VC++ MFC and it follows a document view architecture. I have an application which allows user to draw shapes, zoom, pan etc.
I had drawn a shape. Now using pan tool i had panned the map area, the document as well as the shape gets moved. Now using select tool i want to move the shape, within the panned area, but whenever i am doing that i get a distorted kind of image which is not correct. In normal case its working fine i.e. if the map area is not panned. Can anyone please help me out with the same.


Thanks in advance.
