Hello,
When working on animations, I very often use both Live Link and the 3ds Max Curve Editor. Not sure what the cause is, but when Live Link is active, the Track View Curve Editor becomes basically unusable - unresponsive. The issue resolves itself once I stop Live Link. I suspect some kind of interface/display glitch is happening, though I’m not sure whether it’s more of a Vantage or a 3ds Max issue.
