I have the latest graphicsdriver, latest installers, latest everything. I've tried disabling x-ray and it didn't work (not sure if I restarted SOnar though, if that's needed.
BUT....
It seems to be working better in Sonar X2. At least so far. I've had times recently when it has worked better as well but then started with the weird behaviour again. So it might be a bit early to tell. But all tests have worked so far.
I've even offered Waves to send them a video I made of the problem. But they dont seem interested.
They say they never experienced the problem and it's working fine on their test setup. That obviously is enough for them. I think it sucks. Because on their DAW-compability site it says X1 is compatible.
I also noticed that their NS1 noise reduction worked MUCH better under Sonar X2 for some weird reason. And I'm not talking about the GUI here but sound. In X1 I had to pull the slider up to 80% to get rid of the noise of my guitar. But on X2 20% was enough.
And yes, I was testing with a clean new project with the default template. So no weird settings messing about...
