I can't scroll lists in panels or drag cursor to draw when in canvas area

I found that after I updated Umoupen to 0.9.56, bld 570; I can’t use my cursor to draw, use lasso, use the select/move tool, or erase; unless I use sidecar (when you screen mirror a Mac to an iPad) to draw. I also can’t scroll the brush categories list or the color picker

(I occasionally use sidecar because my drawing tablet hasn’t come in yet, but whenever I don’t use my iPad for sidecar I try to draw with the cursor.)
