If I have a virtual machine window on an external thunderbolt display, it dies instantly (crashes without a sound or any kind of alert) when I unplug the thunderbolt cable from my Apple MacBookPro. Maybe it has nothing to do with external display, but with something else I use over that Thunderbolt link (ethernet connection, usb keyboard and mouse, external hard drive in a thunderbolt dock). But it definitely didn't happen before. Host computer is Apple MacBookPro 15"" non-retina Mid 2012 (MacBookPro 9,1) with 16 GB RAM, 480 GB SanDisk SDSSDXPS480G, Nvidia GT650M, running Mac OS X 10.11.6. Guest machine is MS Windows XP SP3, 3GB RAM.",defect,closed,other,VirtualBox 5.1.26,fixed,crash external monitor thunderbolt,smayoo@…,Windows,Mac OS X
