By freezing does that mean you are getting Poser 7 (not responding) in the upper left part of the app window and the program appearently doing nothing?  I've been getting that for over a month now.  Try waiting it out for 5-10 minutes and see if something eventually happens.

I'm thinking of reinstalling, but somehow I doubt that is going to help.

WARK!
