I've tested Photo Wizard and couldn't identify the exact procedure that you've mentioned in your question. The software allows zooming through the Enhance button, but that's primarily used for viewing. Another application needs to be installed to zoom and then cut the application.
For example, XnView allows you to do that and it's way more powerful than Photo Wizard. Install the application, then use Control + Mouse wheel to zoom, drag and drop to select the area, right click and CROP. Save the new file to the desired format and name.
