Process Still Active after Calibre Closed

[country0129]

I'd queried the forums the other day concerning what I thought was excessively high CPU usage when converting Ebooks.

You folks have alleviated my suspicions of something amiss with the problems I cited. However, I did surface what I think is a glitch with the new upgrade: I "X'd" out of the program after trying to convert one of those pesky *.pdf books, crunched it for about 45 minutes, and I gave it up for a lost cause.

I abandoned anything I was doing with Calibre and started doing something else simple, like checking email or something, I forget. I noticed that the 'puter was a little sluggish; so I opened the task manager to peruse open applications. Nothing amiss. However, when I opened the process manager, I found two Calibre applications still running though I'd closed the program. Each of them was still trying to render the *.pdf's I'd been working earlier. Wish I'd have jotted down the name of the process, but I do remember it was something like, "pdfconvhlpr" but don't quote me about that. Just it was weird that Calibre still had a process going after the progam had been "closed." It was nothing important, for it was easily stopped, but I thought the developers might wish to know it.
