Thank, this works great!

It does however not work properly when enforcing square selections using the shift key or subtracting ROI with the alt key, because the shift/alt key will make ImageJ show the pixel position of the mouse pointer instead, so the status bar flickers quickly between these two views when moving the mouse. I suggest that the "press shift or alt key to show pixel position" functionality should now be removed, since it is no longer needed; the pixel position will always be shown both for ROIs and the current mouse pointer with this new version.

This is the way the latest daily build (1.51u7) works.

The daily build shows mouse pointer coordinates this way.
