Description
A VM with "Mini Toolbar: Show in Fullscreen/Seamless, & Show at Top of Screen" set.
While the VM is running, the toolbar appears to have "Always on Top" set, and appears over the top of other programs running on the host, even when the VM does not have focus.
WinSpy++ (allows peeking at Window attributes) says about the toolbar window: Extended Styles: 00080088 = WS_EX_TOPMOST + WS_EX_TOOLWINDOW + WS_EX_LAYERED If I attempt to clear the WS_EX_TOPMOST bit (using WinSpy++) it can't be changed.
https://msdn.microsoft.com/en-us/library/windows/desktop/ff700543%28v=vs.85%29.aspx?f=255&MSPPError=-2147217396 says: "WS_EX_TOPMOST 0x00000008L The window should be placed above all non-topmost windows and should stay above them, even when the window is deactivated."
I suspect that WS_EX_TOPMOST should be cleared when the VM window loses focus.
Host : Windows 7 SP1. Guests : Windows 8.1, Windows Server 2008 R2.
