ernyoka, Unfortunately the Interlok Sector 0 header is written, certainly by the Poser 5 CD initially shipped. It is highly probable that a later pressing of the CD, with SR2 already applied would not do this (to avoid the royalty payments to PACE for a feature CL wasn't using, if for no other reason). But whether there exists such a later pressing of Poser 5 I do not know. I'd like too, because if it does, I'd like to ask CL for one so that I can consider a full re-install of P5 (to see if it works any better with respect to the dumb floating separate focus parameter window). All the info about the Poser 5 SR2 and Interlok was here on R'osity posted by CL in the Poser 5 Beta forum, but all of that was deleted by R'osity ASAIK. CL was very clear at the time that SR2 does NOT remove any Interlok code at all ,in fact leaves it present, correct and running - for the reason I mentioned above. (They just dropped the links to it out of Poser 5 SR2 - and above.)
