I'm trying to change my animations using the Animation Editor. There are two inconveniences I'm facing and I would like to know how to fix them.

First is where I suddenly become unable to drag and select multiple keyframes or change interpolation, when selecting individually. I've attached a video to showcase the issue. I am able to fix this by restarting the Houdini, but it only seems to work some times.

Second is that upon making a change in keyframe values or moving the keyframe around the timeline, the interpolation changes. And I'm forced to set it all over again.

I'm using Houdini 17 Apprentice. Please let me know if I should provide any other information.

Thank you.

I think I'm having this problem too from time to time. The cursor seems to be disabled, but it's changing the slopes (although the tangent handles are not visible). Houdini Limited Commercial 18.5.633

Restarting Houdini fixes the problem. It's hard to reproduce, unfortunately.
