Uncertain on where to report the bugs.
Within Daz Studio 4, all versions and working with M3, M4, V3 and V4, when I add and remove morphs (one right after the other to see how they would look on the character) my computers freezes up after approximately adding and removing the fourth morph. I wait a minute or two for the computer to respond again, but eventually I have to do a force shut down. When I'm working with Daz is the only time my computer freezes up.
I have Windows 7 home premium with 64 bit Operating system and 4 GB of RAM
