I just noticed that MC seems to lose focus. The bottom taskbar appears and the cursor keys won't work unless I use the mouse and click inside Theater View. Seems like odd behaviour to me.
I've seen that too! It's very important that this doesn't happen. In particular for those of us that use a remote.
Edit: In most cases I've seen, the focus has been lost but the taskbar has not appeared. The only indicator is that the remote doesn't work.
The losing focus thing may be unrelated, not sure.
I'm not on the same platform, but have similar setup - booting into TheaterView, or resume from sleep into TheaterView. Whenever it has happened I think the focus is lost because something else grabs it, it seems to happen for me only when something else announces that updates are available or they have a problem initializing, once it was AnyDVD, once Adobe, once Apple, regular Windows Updates, etc. Seems that the taskbar programs grab the focus, needing a mouse click in MC. Each time it happens, I go round the programs to disable the auto updates or notification, so now I lose focus less often.
Does pressing the Green Button on the remote bring the focus back? I keep meaning to check, but keep forgetting because my wireless keyboard/mouse thingy is too handy! If it doesn't, you could always program an unused button on the remote to bring the focus back.
