This is going to sound crazy...but optamizing is the first thing it does..so it hung up right away.
Sometimes mine will hang..like it just forgot what it was doing..or took a nap or something.  :D

So what I do is start some other program..like a game of solitare or something like that..some little something that won't take a lot of resources or crash everything...and usually Daz will unhang..its like it needs to be woke up...lmao..
I told you it would sound crazy...but it works for me every time...and I don't question it if it works.
