This has been my biggest issue with Boris. I have the problem in Boris FX7, most often when copying and pasting keyframes of Spline Objects. Not only doesn’t the copy/paste work correctly with Splines, but it inadvertantly modifies other keyframes that shouldn’t be affected, and sometimes adds extra unwanted keyframes that then behave bizarrely. I sent a file to Boris and they confirmed the issue months ago but thay have done nothing to fix the problem. In trying to create animated masks with Spline Object, it becomes a major problem.
