Pulse (3.3.56.0) leaks hidden TNewsBodyForm windows:

(you can't tell because Spy++ is not very good but those are all windows that I've "closed")
One effect of this is to make Adobe Reader appear to be leaking memory

It also fails to delete its "Pul*.tmp.pdf" files from the temp folder on exit.
On a related topic: is there any good reason why news windows can't be docked?
