when i right-click to open the menu, left-clicking outside of the menu doesn't close it, like it should. and subsequent right-clicks open up more menus. the only way to get rid of them is to choose an option.
I am not getting the bug that you are getting, but I am getting a different kind of right-click bug. When the right-click menu opens below the cursor, it works fine, but when it opens above the cursor (when I click on the lower part of a page) , the right-click menu disappears upon mouse release.
