Taskbar becomes a gray line due to incorrect sizing.
Cause:
The Taskbar has been incorrectly sized. This may occur when many programs are running. The Taskbar automatically grows to accommodate the number of buttons.
Solution:
Resize the Taskbar by dragging the double-edged pointer to the desired location.
1) Position the pointer on the edge of the Taskbar until the pointer becomes a double-arrow.
2) Click and drag the Taskbar to the desired size and release the mouse button.
