How do I close holes in a selection?  Image->Selection->Fill ROI Holes
does not work.

e.g. create an image with this code:

newImage("Untitled", "8-bit black", 1024, 1024, 1);
makeOval(252, 293, 390, 376);
setForegroundColor(255, 255, 255);
run("Fill", "slice");
setForegroundColor(0, 0, 0);
makeOval(402, 430, 148, 143);
run("Fill", "slice");
run("Select None");

Then create a selection from that image:


run("Auto Threshold", "method=Shanbhag white");
run("Create Selection");
roiManager("Add");

From here, Fill ROI Holes does nothing.  How do I fill this hole?
Thanks
-Ed
