MAC PRO (Snow Leopard) running Symphony 5.5.3 using Stagetools Moving Picture plug in.  I get system freeze when the Moving Picture plugin is embedded and has lost it link.  My Media composer are fine.  Only is happening on my MacPro.

I've rebuilt the system serveral time over the last few days and even a very lite install as the same results.

System ID on the Mac Pro:
