Since upgrading to 6.5.2 (x64) I’ve had A LOT of problems when closing projects. 9 out of 10 I have to hard quit the program through the Task Manager. FYI, I’m using Windows 7x64 SP1. I’ve tested a lot of projects as I suspected it might be a plugin-bridge related issue, but I couldn’t find a pattern there. It wouldn’t close properly regardless of the plugins used.
