Dear Rick,

With the latest version, 1.05 beta, this is reasonably easy to do. The new TImageScrollBox.MouseMode property when set to mmSelect will allow you to select a region interactively. In the Demo.Exe when you set the View|Mouse Mode to "Select" you will see the selection mechanism. Once a selection is made a TDibGraphicPrinter object may be used to print the selected graphic.

Thanks for the comments on the installation short cuts. This is something I took for granted. I'll see if my installation program has this as an option. My help writing program does not have a spell checker, so I apologize for the spelling errors. I also hope to improve this in the future.

Best regards,
