Hovering over panel items with mouse button pressed?
With a horizontal xfce4 panel on top of the screen, is it possible to (horizontally) hover over the different items (widgets) in the panel with the left mouse button pressed and the pull-down menu of the pull-down menu of the item getting into the mouse focus gets opened and closes when the mouse pointer moves over a different icon? I can open the menu of an item with the mouse button, but when I move the mouse pointer away it stays open and no other menu can be opened. This is probably not a bug, but still it would be nice to be able to change that behavior.
