cancellation of backgroundWorker does not work as expected

Allright here's an error i found, if you cancel (close the progress window) it 
calculates the number of books done so far (25 in this case) then asks if you 
want to view the log... problem is it's still running the process in the 
background and i guess the file is locked because it's still being worked on.

Did you account for cancellation with the background worker?
backgroundworker.Worker.SupportsCancellation = true

and send cancel on the progress window close?
backgroundWorker.CancelAsync()

and allow for cancellation in the BackGroundWorker.DoWork Event by enclose the 
entire process in a if statement?
if not backgroundWorker1.CancellationPending:
