I updated to Brave 0.18.23 on Windows and it has a new problem that arises intermittently and keep coming back.
If I open a new window (as opposed to a new tab), the right-click menu in the new window simply does not appear. It appears in the tabs in the old window. I use dual monitors and this is really frustrating, since I often want to right-click on a link and open it in a new tab.
If I exit Brave completely, then the problem goes away for a while but comes back again.
