Maybe someone here will know, but I would suggest you ask the folks at MikTeX. It is possible that MikTeX wants to upgrade some package or other. Apparently, it does this sometimes. Possibly, there is some background image conversion of something that is triggering it. It seems to be possible to turn this off somehow in MikTeX configuration, so you might try that. Riki
