...  Actually, I just looked over my own ImageCanvas.java modifications,
and I found that I must have previously encountered the problem because
I had implemented a solution in my copy.  It also seems to solve the
problem by modifying a different method to limit accessible ROIs to
those in the current slice:


     void drawAllROIs(Graphics g) {

...
//        if (labelRects==null || labelRects.length!=n)
         labelRects = new Rectangle[n];

...
             if (Prefs.showAllSliceOnly && imp.getStackSize()>1) {
                 if (hyperstack) {

                     int c = roi.getCPosition();
                     int z = roi.getZPosition();
                     int t = roi.getTPosition();
                     if ((c==0||c==channel) && (z==0||z==slice) &&
(t==0||t==frame))
                         drawRoi(g, roi, drawLabels?i:-1);

                         labelRects[i] = new Rectangle(roi.getBounds());
                     }
                 } else {
                     int position = roi.getPosition();
                     if (position==0)
                         position = getSliceNumber(roi.getName());
                     if (position==0 || position==currentImage)
                         drawRoi(g, roi, -1);
                         drawRoi(g, roi, drawLabels?i:-1);

                         labelRects[i] = new Rectangle(roi.getBounds());

                }
             }
         }
         ((Graphics2D)g).setStroke(Roi.onePixelWide);
     }


I also found one error in mousePressed(e) that can mess up the clicking
of ROIs in edit mode when the image is zoomed in or out:

the line
                 if (!(roi!=null && (roi.contains(ox,
oy)||roi.isHandle(x, y)>=0)) && roiManagerSelect(x, y))


  should read
                if (!(roi!=null && (roi.contains(ox,
oy)||roi.isHandle(x, y)>=0)) && roiManagerSelect(ox, oy))


Best,
Bill
