I like many of the new features (face lab, material lab, hair lab), but have to admit that I haven't had a software actually completely crashing that much for quite some time. Windows keep being opened and cannot be get rid of, buttons don't react any more - I have sent bug reports to egisys already, but doubt that there will be a chance to see patches soon, it seems there is just so much to fix. Anyway I am not downgrading to P4 as I think Poser is now slowly becoming the App I wanted to have when buying Poser3...
