While I agree that CL is in a no-win situation over Interlok for us dumbies who bought the early copies, they SHOULD have replaced the retail CD master copy now, so that they don't keep installing Interlok on the systems of new purchasers, should they not? (After all Kupa has said he knew a major fix was need before P5 release so they shouldn't have made that big a first run CD imprints - particularly as they didn't even QA that all the files were on the CD master tape!!!) Re the firewall blocking, Poser is quite happy if ZoneAlarm is set to block entirely, but P5 (not P4) can sometimes get it's-nickers-in-a-twist if it's set to ask. It seems to be a question of responding to ZoneAlarm's prompt before P5 times out the internet connection and tries again - and screws up the retry. Don't have Norton firewall, but default-guy was reporting a problem with P5, and suggesting to not block fully - his message should still be in the SR-2 forum, it was one of his last few messages around the time he left CL, just before it became a near-virtual co.
