I read on another forum that DAZ Studio will not use the injection system, but they didn't explain how. I think we'll find out soon, but I suppose that the program will access the deltas in the !DAZ folder directly. (?) Anyway you are right if you only have Poser 4 it painful to use the injection system. I had to create afake runtime to store all the stuff I didn't need at the moment so that I only had V3 folders in the pose directory... :( Poser 5 helped a lot, but I have to admit that I didn't have a lot of problems with it because I really use Poser 5 as if it were Poser 4 (no firefly renderer, no hair room end so on). But the folder management system is a must have...
