This function is used to cope with pop-up stopper programs. If the user chooses to

the download window. But if a pop-up stopper is lurking in the wings, the child window
will appear and disappear quickly. This function will be invoked to check for that condition
by monitoring the condition every quarter-second (250 milliseconds) and redirect the user to 
the standard download page if it occurs.

NOTE that the user can close the child window after the download has been completed. When
that happens, this code must be disabled. I'm using a time interval to determine this. If the
window is destroyed less than (say) 2 seconds after it was created, assume it was destroyed by
a pop-up stopper and perform the location.href statement.

Late update. Certain popup killers appear to disable parts of this java code. The child window
handle remains valid but newchildwin.closed is not true. The error condition is triggered when 
location.length is used and causes a redirect statement to be executed.
