I ran again into this bug, with the 1.44i daily. It happens if I press the  
Alt key during such a for loop (simplified to illustrate the point):

for (...) {
        makeOval(..);
        roiManager("Add");
        makeOval(..);
        roiManager("Add");
       
        roiManager("Select", roiManager("count") - 2);
        roiManager("Rename", "r" + i);
        roiManager("Select", roiManager("count") - 1);
        roiManager("Rename", "b" + i);
}

Maybe some kind of race condition?

Best,

Janne
