Moisheh,
Which Windows do you have? I have 7 and 8 and my banda ancha window does not go away. When you open your email program or internet browser the banda ancha will stay in the background if you do not click the shrink bar at the upper right of the banda ancha window. If it does go away there should be an icon down on you task bar - could be left or right - on the right it could be you have to open additional icons to have it show. If you do not see the icon there may be a little UP arrow thingy next to the icons on the lower right. If you click that it will open a box with more icons. My banda ancha icon is a tiny little computer - click to open - may have to double click. I does get easier as you fool around with it.
