I've been surfing the forums for a while now because I am still unable to get Coherence to span 2 displays (primary and external). It appears that some get it working, and some don't. I've found that mostly it works on macbook pros. So I'm trying to narrow my search....has anyone been able to get coherence mode to span more than one display on a macbook? I was hoping this was fixed in the latest build but it isn't, and the documentation doesn't have any info about Coherence and how to config it. If this is a parallels issue, then that's fine, but I want to make sure I'm doing everything right on my end. I have a 13" macbook 1280x800, and a 19" monitor 1280x1024. I have confirmed that they are aligned correctly within the "Arrangement" area of display prefs in OS X. I have tried to use Coherence with my toolbar on the macbook, or the ext. display. Each time, Coherence only works on one screen. I have enabled multiple displays but when I turn Coherence on, I get an error stating that Parallels can't run coherence because the client doesn't recognize the resolution. I have tried adding a custom resolution within parallels by adding up both resolutions and making one big one, but Parallels rejects it. Am I missing something?
