immunize seems to be 'stuck"

i'm on the beta version. the immunization seems to be stuck on IC 32 bit software domains with 14961 unprocessed. any idea why it takes an hour to do this one line (and it's still not complete)?

I had a similar problem with the immunisation appearing to get stuck on the Thunderbird entries.

Eventually, I let it run and it sorted itself out. Once it had immunised that first time, all subsequent immunisations have been quick.

I had had Spybot v1.6.2 installed prior to installing the beta, so it may have been that the beta was somehow confused by existing entries, but once it had got them into a new format everything is fine.
