Is there ever a circumstance where a current instance of a window would not
have a handle?
Also, I was under the mistaken impression I could pass the window function a
handle and it would return a reference to the window with that handle...
After re-reading the Language Reference, I realize that I was misunderstood
that function. Is there already a function that will return a reference to
a window when passed the window's handle, or do I need to just make my own
that will loop through all the windows and check their handles for a match?
