I just bought P8 this morning.  I have been using Poser since version 2.  My issue is with any message window that pops up.  I have installed SR1, but with P6 and P7, I have never had this issue.  Anytime a message window pops up (ex. Deleting just one light with only Andy loaded) and I click either Cancel or OK, P8 just locks up.  I even switched over to SreeD to see if that would do anything, but to no avail.

Has anyone seen this problem?
