Non reproducible bug on ImageJ

Dear all / Wayne,

I have got some trouble with an issue on both ImageJ and Fiji that on top of
this isn’t even reproducible which could make it very tricky to fix.

So let’s consider the following short macro code:

run("Blobs (25K)");

makeRectangle(83, 41, 94, 159);

run("Crop");

close();

run("Blobs (25K)");

run("Restore Selection");

So sometimes this code finishes with the Blobs picture open on which the
previously defined ROI (i.e. makeRectangle(83, 41, 94, 159)) is selected (as
expected).

But sometimes it finishes with all the picture being selected (i.e. similar
to run("Select All")), and this issue is connected to the fact that there is
a “run("Crop")” within the code.

This problem has now no consequences for the macro I was developing since I
finally use a getBoundingRect(x, y, width, height) to get the rectangular
ROI position and sizes and apply later on the copied values with a
makeRectangle (x, y, width, height) instead of a run("Restore Selection").

But it took me quite some time to figure out the origin of the issue and it
may as well be problematic for other users.

My best regards,

Philippe
