Hi all,

- File > Open Samples > Fluorescent Cells (400K)
(make sure the image is displayed as composite 3-channels, which is the default)

- Image > Transform > Rotate 90 Degrees Right
Nothing happens to the displayed image.

The image got rotated in memory though, as seen by:

- Image > Duplicate...  (with 'Duplicate hyperstack' checked)
which results in the display of a rotated image.


Or, to reproduce, run:
// ImageJ macro language
run("Fluorescent Cells (400K)");
run("Rotate 90 Degrees Right");
run("Duplicate...", "title=FluorescentCells-1.tif duplicate channels=1-3");

and compare the two open images.
