| Hi Dawn,
You can try toggling the check boxes which appear in the option bar across the top of your screen after selecting the zoom tool. Also check the Edit>Preferences>General setting for resize windows, and the minimize / maximize check box on the top right corner of the window, and the screen mode at the bottom of the main Tool Bar. If nothing works to correct the problem, then it is possible that your PC Prefs file may be corrupted. If this is the case you could reset your prefs by holding down the Shift + Ctrl + Alt keys while starting Photoshop.
