  Initial checking for multi-region all-windows warn. This is an attempt to handle timeout high-level errors better, when a track is taking too long to finish loading; and to handle the network errors across all of the windows together, i.e. using the entire screen width to display the errors, only diplaying the first error, and only drawing for the first window.
