16246	In seamless mode, mouse events do not reach host windows visible behind the VM -> fixed in 5.1.28	j-za		"In VB 5.1.10 on an OS X 10.10.5 Yosemite host, when a Windows guest (Win 10, XP) in seamless mode has focus, clicking a host window that is visible ""behind"" the VM has no effect.  Normally that would switch focus to the app that was clicked on.  

Other mouse events that normally affect visible background windows (scrolling in particular) also have no effect. 

Using Cmd+Tab works normally to switch to another app, so does clicking on the Dock icon for another app.  Clicks on the menu bar also work as you'd expect, and so does clicking on any window that belongs to the foreground VM.

The abnormality can be confirmed using the OS X UI Element Inspector app, which reports attributes of the widget under the mouse pointer.  Normally when the pointer is over a background host window, details of that window are shown.  In this case however, it hardly matters where the pointer is: the entire screen is reported as a single screen-sized window owned by the VM, except for the menu bar and the Dock.  

For comparison I tested versions 5.1.8 and 5.1.6 against the same VM's: neither of those showed this problem"	defect	closed	GUI/seamless	VirtualBox 5.1.10	fixed	seamless mouse		Windows	Mac OS X
