Apologies for resurrecting, but:
I just installed Win 7 on this machine yesterday, and so I've been reinstalling apps. And I don't remember which SVN of XBMC I was using before that allowed for secondary-monitor support.
Here's the issue I'm having right now: with the couple of SVN's I tried, when I change the setting for it to go to the secondary display, everything goes back, and then after a few seconds it comes back to the primary screen, but the secondary one stays black until I mouse over and do a right-click-Refresh, at which point it comes back to the extended Desktop.
(Oh: Radeon 4850, newest Catalyst drivers for 64-bit Win7, if it helps.)
Has this happened to anyone? If so, is it solvable? Am I missing something?
(Can I maybe edit a settings file so it will already be set to that when I boot XBMC? It's sure acting like it doesn't care for the monitor switch, but I don't care if I can just get it launching in the second monitor and be done with it.
)
Thanks much!
