Ok first make a nice rectangle

doesn't really matter what colour...
Keep the background white of your scene...
Ok now goto your movie settings
and select the grid function and snap to grid function
Select your rectangle tool again and make a liniear gradient choose 100% black and 0% white ( this is to make the end blurry so it looks more real )
Take your reshape tool

and take the bottom left point and drag it up 2 boxes ( it will automaticly snap to grid )
Do the same at the bottom and also select your reshape tool and drag the upper right corner 2 boxes to the left.
Now take your rectangle tool again and make a rectangle with these settings [img]
about 2 boxes wide
So the left colour is 100% white and the other colour is 0% white so it blends in with the background)
Copy that rectangle and drag it to the corner and rotate it until you have the same result as shown in the image below.

Copy it again and drag it to the top and rotate it until the 100% white colour is on top and the 0% white is over the black gradient
Now your all done and your info box should look like this
With the big rectangle on top
If you are using a different background colour besides white change all the white colours in the gradient to the same colour of your background otherwise you will notice a white glow around the edges and the shadows will not look real. Haven't found a solution yet when you are using a background image with different colours/paterns in it.If you can't follow it or something is not clear plz reply
