bucket fill seems to be having random lock ups, or inability to function normally.

When I open a new layer and try to use the bucket fill nothing happens. I am an experienced user--20 years. This has never happened to me before. Tried numerous work arounds but it just wouldn’t fill. trried opening new layers, but still didn’t work on any of the layers. Tried saving the project and removing unused layers. But still the bucket would not fill. Finally just used the paint brush to paint the layer. 

Otherwise, I love the beta and use it  almost exclusively over the regular Photoshop.
