Hi Nico,

ImageJ shows the progress bar only for some operations, mainly for those that are slow with more "typical" image sizes (0.1-10 Mpixels). Your output image has 100 Mpxl.

Resizing is done at a rather low level (ImageProcessor) and it is just a small part of the operation in several other commands (e.g. "Make Montage"), so adding a progress bar for resizing would give a meaningless (or flickering) progress bar for other operations that use resizing. So ImageJ just shows a status message when resizing, counting the images that have to be resized (for the case that a stack is resized). Unfortunately, that status message goes away as soon as the mouse is moved over an image, it yields for the coordinates & value readout.
