Whether background transparency is available or not depends on whether 
the graphics driver supports it or not.  My guess is that you haven't 
installed the graphics driver for your graphics card yet.  I believe 
that if you run Windows Update, a graphics driver for your card will 
available as an optional package to install.  But instead, I recommend 
to go directly to the vendor's website and download and install the 
latest driver.

     Good luck,
