My host is headless Rhel 6.7 Server. I sometimes use X11 forwarding to run the GUI.
Recently I upgraded from vbox 4 to version VirtualBox-5.0-5.0.16_105871_el6-1.x86_64.
I noticed that when I type "VirtualBox" in shell and then close its window the process remains running. Then I noticed that there's another hidden window in taskbar.
I have to press Ctrl-C or close the second window to end the process.
This only happens when I connect from Windows and use cygwin xwin server (but not xming)
The visible window is captioned "Oracle VM VirtualBox Manager@hostname" and the hidden one is captioned "VirtualBox@hostname"
It's not really hidden. There's a white pixel at the top-left edge of my second monitor
When I start VirtualBox, some messages appear in XWin.0.log:
Code: Select all
