When you open a program it will minimize right away to the start bar and you cannot get the program to show on the screen. It just sits there, minimized!
Some programs simply react this way for a number of reasons. The work around for this issue: With the program seemingly minimized, hold the arrow over the icon on the start bar, hold down Shift and right click. Then click on the Maximize option and it should open to full screen and you will be able to use as normal.
