@JoePublic.

I like mastersync, I find it useful while setting up complex dependencies. Negates the need to back out certain values in sub masters. Obviously you found the off switch but it's easy as all get out to turn it off.

Also... this statement intrigues me...

I also made sure to have a copy of Poser 11 as a last ditch backup that will keep on working regardless wether Poser ever changes hands again or more likely turned into abandonware due to a lack of interrest.
