Blocked Startup Programs not Blocked

(Vista RC1-64)I added a program (Highpoint Raid Manager) into the startup
folder.

Now Windows defender tells me on boot that it has blocked the program which
it shows as "Not Yet Classified". In fact it hasn't blocked it at all (which
is good!)

If I try to select the program in the Software Explorer list of startup
programs, I'm only offered the options of "Remove" or "Disable". How am I
supposed to indicate that it's an OK program to start and not to check it any
more?

(at the moment this is merely an annoying message, with no functional loss,
but I suspect that one day Defender will be 'fixed' to really block it)
