Cancel close event when WFS

If WFS is running, being a time consuming task, if the close event is raised while running CCleaner should alert the user to abort or continue.

+1 I agree (while still maintaining that WFS is evil B):ph34r::wacko: )

+1 to both of you.

Just a minor inconvenience while using it.

It's not evil. It has it's uses. Just needs to be moved to tools.
