Hi Douglas,

the problem is NOT partial copying on "Duplicate", it is just the way  
how ROIs are displayed on the screen.

At 100% zoom, the yellow outline is inside the ROI at the top&left,  
outside the ROI at the bottom&right. At higher zoom levels (say,  
400%), this 1-pixel-shift is less noticeable.

It is the same for the outline created by typing CTRL-D (Draw),  
irrespective of the zoom level.

Michael
