Sigma 10-20 doesn't focus in live view on D7000

Has anyone else experienced this? Just tried last night, AF does not work (it tries to focus, but always ends up out of focus). Focus through the viewfinder is flawless.

Not a big deal, as I don't think that live view focus is worth much anyway, but still a bit annoying. Anyone else have this lens with the D7000 who can confirm?

Cheers
