Basically when you right-click the menu flashes up and then disappears. If you are experiencing it, you would know it. The reason I mentioned that the right click menu in Chrome was fine was to commuicate that it does not appear to be either a Unity/Gnome issue in general or a mouse hardware issue with the button etc. IMHO, it is definitely an issue with the DR GUI on Linux (Ubuntu). Hmm, I can do a quick Fedora test as well.<div class="gmail_extra"> <br><br><div class="gmail_quote">On Fri, Nov 2, 2012 at 10:18 AM, Laurent <span dir="ltr"><<a href="mailto:laurent.orseau@gmail.com" target="_blank">laurent.orseau@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> Shouldn't you click and stay clicked for the menu to remain visible?
