Yes, it would drive you nuts.

What about a slightly underexposed slide (this can produce a better result
when projected). I assume the long exposure  would help.

How about an irritating pop-up that explains the problem when you select it.
I just tried it with a slide that's been causing me grief and it appears to
have worked quite well and I can't see any nasty side effects. I admit that
right now I'm not a customer, but having tried in vain to get a decent
result with Silverfast I found Vuescan much better first time.

See:

http://www.greenbank.themutual.net/artixscan4000_noise.htm

I've come to the conclusion I will have to buy Vuescan too. The long
exposure looks quite useful to me in the right circumstances.

I believe some scanners (SS4000/A4000T) do not position themselves too well
for multipass - so this is of limited use. I just tried 8x MP with the
artixscan 4000 and there are echos in the image. The result is pretty
useless.
