[dba-Tech] Programs Opening and Closing

Weird thing happened today.  Before today when you clicked on an icon, the
screen would immediately appear.  Now when you click on an icon the screen
fades in, when you close the program it fades out with a "twist" fading off
to the bottom of the screen.  Apparently a Windows update was done this AM.
 Any ideas as to what setting can stop this behavior?
