Inconsistent Fusion Timeline

In Fusion, the spacebar stops and starts playback SOMETIMES. At other times I have to click the transport controls to stop and start.

In Fusion, HOME will not move to the first frame.

I don't know if these inconsistencies are a "feature" that I'm not aware of, a problem with my machine, or a bug.

Thanks,
Dave

Got the solution from a gentleman on Facebook.

The cursor must not be in a text field in the inspector. So, I just click in the nodes area and then the spacebar works fine.

this is also true on the edit page.
