All of a sudden, the emails I am dial are a building block in the middle of the screen.  I can't minimize or move the drive to refer to another email.  Must send to the project folder.  Boring!  Why is this happening?

Hello!  All of a sudden, the emails I am dial are a building block in the middle of the screen.  I can't minimize or move them if I need to take a break to refer to another email.  I send email partially completed to the drafts folder.  It is extremely annoying.  How to do this?  Operating system is OS X Yosemite (10.10.5) on a MacBook Pro.   Thank you!

You are using the full screen? Try the command - command - F.

Try a reboot.

Make a backup using Time Machine or a cloning program, to ensure that data files can be recovered. Two backups are better than one.

Try to set up another admin user account to see if the same problem persists. If back to my Mac is enabled in system preferences, the guest account will not work. The intention is to see if it is specific to an account or a system wide problem. This account can be deleted later.

Isolate a problem by using a different user account

If the problem is still there, try to start safe mode using your usual account.  Disconnect all devices except those necessary for the test. Shut down the computer and then put it up after a 10 second wait. Immediately after hearing the startup chime, hold down the SHIFT key and continue to hold it until the gray Apple icon and a progress bar appear. Startup is considerably slower than normal. This will reset some caches, forces a check for directory and disables all start-up and connection, among other things. When you restart normally, the initial restart may be slower than normal. If the system is operating normally, there may be 3rd party applications that pose a problem. Try to delete/disable the third-party applications after a reboot using the UN-Installer. For each disable/remove, you need to restart if you do them all at once.
