@Kovid, When in Viewer - Preferences - Styles: Previously I was able to highlight text in the edit box, right click and copy the text. Now when in the Preferences - Styles - edit box if I right click it acts as an escape and takes me back to the main preferences window. I can use Ctrl-C to get the job done, but right clicking to copy is intuitive. When you get a chance check it out.
