#435 Pause control not found; ? risk in aborting downloads?

[Chloe47]

Returned from vacation. Currently downloading #15 of
51 in catchup mode. AND update to Windows
available. AND update to McAfee downloaded, wants to
install and RESTART! AND MS AntiSpyware wants to
update.

I want to stop after the current downloads complete -
DO NOT START NEXT DOWNLOAD! or

I want to "undo" and abort the current downloads, so
they will restart "normally" another time. or

I want to "Pause and Resume Later" (one function?
separate [manual?] operations?) but

I would prefer not to "lose" access to a feed, or
an "episode", etc.

Thanks.
