Unable to right click on timeline (Adobe Animate)

[peterg99415245]

When my arrow is over on the timeline, a little white square appears to the lower right side of my arrow and it won't allow me to right click (to access the copy frames, etc drop down menu).

Any ideas on how to fix this?

I see the same small white square here but can right-click. What platform are you on and are you using any kind of pen display tablet? If so, what kind?
