I have run into an odd bug or issue with Poser Pro 2010.  Sometimes, the program appears as if it has crashed, being unresponsive. When this happened, I was forced to kill the process and restart the program. Often the unresponsiveness would happen again as soon as I'd start the program.

Then I started looking for other processes that may interfere, and found that if I closed Rundll32 Poser Pro 2010 would work as it should the next time I started up. Then I realized that when the program stops responding, all I have to do is to go into the task manager and close the Rundll32 process, and it responds again (no restart of the program needed) It seems to happen most often when I start another program, while PP is already running, like Chrome or such. 

Has anyone run into this as well and know of a solution of what may be causing the interference?
