My mouse cannot scroll in the Saved searches pane, unless the cursor sits on top of the vertical scroll bar.
It behaves as expected in other panes. No need to put the cursor on the scroll bar, simply anywhere in the pane itself.
And the three-fingered salute still fails to wake up X1 unless I change it between sessions.
For example, this morning it did not respond to Ctrl + Alt + L, which is what it was set to yesterday. But it will respond if I change it to Ctrl + Alt + X.
