Hi Wayne,

Thanks, I think that will be helpful to detect the error.

This strange behavior is due to a bug in the macro interpreter. There is a syntax error in line 9 of the non-working macro that the interpreter does not detect. The latest ImageJ daily build (1.52c12) fixes this bug and displays this error message when you run the second macro:

   ‘[‘ expected in line 9

    roiManager ( “Select" , newArray (c <)> ) ;

Up to adding the combined ROI to the Manager everything is OK but after that the selection in the Manager is different and it does not recognize what is selected and deletes all ROIs. Adding  "roiManager("Select", newArray(c));" before trying to delete ROIs does not work. Adding " roiManager("Select", newArray(0,1,2));" however at this point works as expected. I assume this is a bug?
