I have used FM5 Beta since issue up to the latest 5.Ob44 and I like the interface and new features - it works fine except for masks - when increasing or decreasing mask size with the Zoom control wheel, the mask size is not synchronous with the Zoom wheel - I have to wait until the zoom is complete and then the mask alters to the new size. With FM 4 the mask size was synchronised with the Zoom wheel so that I could see the changing of the mask as the wheel was used. Is this intentional or a bug ? Apart from this, I find the team have done a great job.
