I've had numerous issues too up until now. I've downloaded 4.04.004, I'm on studio 4, installed, and just spent the last 10mins trying to make break it, unsuccessfully. I opened three acoustic guitar tracks, main vox, backing vox, cutting the main vox into 20 regions. That's 5 full tracks, with 20 regions open in the main vox, a total of 24 regions open at the same time, all able to be edited, and it was working at a speed it has never worked for me before, let alone more than one region open, which I havn't been able to do all year.
So, for me it's not just fixed, it's on fire, and I sure hope it stays that way.
So, there must still be individual problems that have something to do with system or hardware. I hope everyone get's it sorted. Been very frustrating.
now, back to work..
