Weird conflict between Zoom In tool and ResizeFcn default behaviour

I have some problems when I try to apply zoom on an axes in my GUI when the figure is full-size screen. I use the default function for the Zoom In tool and I have not written any code in the ResizeFcn function (I only have set the Resize Behaviour to "Other (Use ResizeFcn)") When I apply zoom, the figure stops being full-screen; it's like there is a conflict between the Zoom function and the ResizeFcn default behaviour. Furthermore, when the GUI is full-screen and I zoom an axes with an image, sometimes the image disappears, and a gray image appears in the axes. Does anyone know what is happening? How could I solve these problems? I've tried to modify the ResizeFcn function but I have not found a good solution. Thanks!
