In OpenCV, after zooming on image, how to get back to standard mouse cursor?


I have an application where I crop parts of an image and save them in OpenCv using Python, first drawing rectangles before saving (SSCCE below). Some of the images are very large, so it is helpful to zoom in on them before selecting regions to crop.

The problem is once you’ve zoomed on an image, the mouse cursor permanently toggles to the interactive hand. Then clicking/dragging only serves to translate the position of the image in the window (unless I go back out to full size, but then I can’t draw rectangles on the zoomed-in image).

So my question is once I’ve zoomed in, how can I get from this.
