I don't know if this was fixed in 396 (or maybe one of the intermediate versions after 377), but when I installed 377 (over 4.8 ) it took a couple of reboots before the descriptions and Start buttons appeared on the Scan screen (before that, only the icons appeared). V5, at least in its earliest "final" stages, in my case took a lot of reboots (and a repair) before it became properly functional.
I know that in 4.8, after you clicked on the kind of scan you wanted (usually "local drives"), if you then did a mouse-over of that one you'd get a message something like "occupied". while the others would show something like "unavailable" or "disabled". I haven't checked but maybe they've done something analogous in v5. Oops, no, come to think of it there's a note (can't remember if right there or in the Help file) that says you can do more than one scan at the same time.
