Just to have a more complete picture of what is happening, below I have
copied the output of xev running through VncViewer 1.2 Java Applet for the
following sequence of events: press mouse button 1, press mouse button 2,
release mouse button 2 and then release mouse button 1. As you may see, the
order of the events captured by xev are not the same of what actually
happened.
Best regards,
Rafael Guimarães
