Description
The second screen is black. We use dual monitors and they have worked fine for years. Even with 4.3.18 it was fine. Now, I extend to the second screen in Windows and says it did but it's black. The mouse moves over there. but nothing actually works. The Mac side still seems fine. I thought maybe it was just that computer so I tried a second one and it's the same way.
I'm running Yosemeite 10.10.1 and Virtualbox 4.3.20 with a Windows XP SP3 Guest. The computer is a 27" iMac with i7 and 16GB ram the second screen is an IBM 19" lcd through a thunderbolt port.
