I do not even own V4 as of yet, so I can definately say its not because I installed V4. the last thing I installed into a completely seperate runtime folder was petite Fleur Hair. I too did hit ok when I saw it, and have not had it come up again (paranoid, I keep opening and closing poser) Maybe E Frontier making me paraniod since I did not put in for my upgrade to poser 7.
