@Max.Chen Can you take a look at this thread? It seems to be a sequencer related issue that affects 5.5 and is affecting a subset of users, myself included, making 5.5 essentially unuseable. Is there any way that we can investigate the source of this problem, whether is be hardware or operating system related?
Currently in the process of migrating 2 weeks worth of work back to 5.4.
Any ideas are greatly appreciated.
