I am having a similar problem. except mine seems to be any dialog box pops up and i hit OK or cancel or anything that should make it go away and poser will stop responding and the dialog will not disappear.

I have determined it is something on my machine. This began happening after i got an update from several programs.

my first attempt at isolating the problem was to go to task manager and kill all processes that had me as the "user name". After doing that Poser worked like a charm.

I have since killed several "quick start" type processes and I am currently in the process of trying to track down what is interfearing with Poser.
