I just upgraded to the latest PD9 patch and Mavericks, and now I see the following new behavior: When I CTRL-ARROW to switch between full-screen Win8 guest and OSX host, it USED TO switch both the MBP and external monitors simultaneously, so I could use each OS with two screens. Now each screen seems to need a CTRL-ARROW separately (whichever monitor your mouse is on is the one that switches). Needless to say, I don't want to have to CTRL-ARROW twice just to get two monitors on the same OS. Is there a way to revert to the old behavior? I don't even know if this is a Mavericks or PD9 issue, but I can't find any setting in either that seems to control this.
