Hi Kirk,
Support asked me to post this to the forum as they haven't been able to help me resolve this issue, including uninstalling, resetting the registry keys, and installing a new version (4.5.2). I am running Windows XP SP2 with 1.5GB of RAM. My issue has been that PM hangs when setting ratings (color or stars) from the large preview window. You must use task manager to kill the application. This happens constantly not occassionally. I really like PM, but having worked with support on this for over a month with no resolution, I am about ready to purchase a competitive product, however I am willing to give this one last try because I like PM's functionality so much. If you have any suggestions please let me know soon.
Thanks,
Mark
