Thank you for your post.
This problem has already been reported to our Development and Software Quality Assurance (Testing) departments, and they are aware of this issue. At this time, no additional information is available. When information does become available, I will let you know.
When running FMPA 10 v2 on Windows XP SP 3, it also fails to release FMPA-allocated RAM when a looping script opens and closes windows. The allocated RAM just keeps getting bigger without ever decreasing.
