Surprising behaviour of Analyse Particles

Jeremy Adler
When I run analyze particles with "clear results" set,
it unexpectedly empties the ROI manager, when I expected it only to clear the results table.

The Ij1 macro code creates a ROI that then disappears 2 seconds later, as Analyze Particles runs.
Version 1.52t running in FIJI.


run("Close All");
roiManager("reset");
random("seed",21);
newImage("Untitled", "8-bit noise", 32, 32, 1);
setThreshold(20,40);
run("Create Selection");
setSelectionName("First ROI");
roiManager("Add");
wait(2000);
setThreshold(215,255);
run("Select None");
run("Analyze Particles...", "display clear add");
//run("Analyze Particles...", "display add");
//run("Analyze Particles...", "display clear");
