Changing tracks causes Cubase to freeze playback

Yep, still have the issue. I’ll have a session that’s good. I’ll save it, close down for the night. Come back the next day, and blam! I have an extremely hard time working.

The meter within Cubase doesn’t seem to be spiking. In fact - if I watch the system CPU meter, it DROPS significantly every time. It’s like Cubase is discontinuing processing temporarily.

What’s going on?!
