I have been editing the position of a simple rectangular Mask Path within a Mask object. Select handles, move them to new locations, set a keyframe, repeat. It was working fine for several keyframes, then something changed.

I am now able to select and deselect the handles, but they will not move with either the mouse or arrow keys. Both methods were working fine previously. I cannot edit keyframes I already created. I can't detect anything that is different in the UI.

Is there a lock setting? Did I click a button or hit a key command that disabled editing? If I create a new object, its handles can be moved as usual, but not the existing rectangle.

Did you inadvertently make a new mask?

I can only suggest that you start anew instead of trying to fix this issue - sometimes, it's better to start from scratch instead of trying to solve strange, out of this world issues.

That's the approach I took -- reverted to a previous file and started over. The problem did not recur. Thanks!
