I used my Macbook in client mode, for the first time with an external monitor, and noticed some odd behavior. The playback status display would not update the cue list. The somewhat odd thing is that the command command line and fader cue (even the clock) repaint instantly, but the only way to get the cue list to refresh is toggle [Format]. If I drag the window to my main screen, it refreshes instantly.
The behavior is the same in full or windowed mode, and with the playback tab in either window. I also noticed the browser does not repaint on the external monitor. Fortunately, the channel screen works on the external display, so my workaround is to swap the tabs.
I found the same behavior on a VGA and DVI monitor. Both the Ion and the client were 1.9.1. The Mac was running 10.6.5. What more information can I provide?
Thanks,
Josh
