When adding a list of movies via drag n drop memory hits the roof
I have found restarting Tixati seems to help but I have lots more to be added

You mean dragging and dropping a lot of torrent files from Explorer to Tixati window, or something else?

yes  dragging and dropping a lot of folders from Explorer to Tixati
The memory stays real high untill I restart Tixati then it drops back to normal
