Comment 8 for bug 1423458

Indeed a duplicate of https://bugs.launchpad.net/wingpanel/+bug/1448450, but in fact the same as this one too: https://bugs.launchpad.net/elementaryos/+bug/1367204

I am commenting here just to say that the issue is not completely described in any of these as far as I can tell.

There are two events here:

STEP 1. right and left click on a taskbar icon (keyboard layout, sound, network, power, etc) have both the same effect: a menu is displayed

 (this is a bit unusual and can be seen as a bug since on all other systems I've seen left and right click on a such icon triggers different effects)

STEP 2. to use the menu, one has to click the same mouse button that was used to show the menu at STEP 1.

That's why left click is not working on a menu triggered with right-click and right click is not working on a menu triggered with left click on the icon. That is more than unusual, it's misleading: left and right click have the same effect (menu appears ) but only to a point (to use the menu left and right click are not interchangeable anymore)

Therefore, a solution can be imagined as:

A. right-click should trigger a different effect than left click on a taskbar icon

OR

B. right-click and left click should trigger the same effect all the way: open menu by left or right clicking the icon and select a menu entry with left or right no matter the mouse button initially used to show the menu
