Hi Jon,

when selecting an image, use the WindowManager.setCurrentWindow function, instead of bringing an image to the foreground (which depends on the gui).
Even better, it should be possible to address the ImagePlus directly:

  IJ.run(imp, "Crop", null);

where imp is your ImagePlus (named 'trans'?)
