I have the exact same problem. Everything worked fine until I updated to 9.10. Now buttons like the close editor tab and minimize side tabs do not work. If i click once, the cursor changes to a text editing cursor, then if I click again (being very careful not to move the mouse) it will close. Everything worked perfectly in 9.04. When i updated, the tab coloring looked different and it stopped working.
