> I cannot fathom what implementation could be so complex that they can’t achieve full test coverage on something like whether or not a damned window appears when required. It does seem that complicated from my observations. Notice that it's not a regular window, but part of the overriding/overlayed renderer (DWM? something else?) that draws stuff on top with grayscale smoothing (Direct2D? DirectWrite? something else?)... which probably involves lots of communication between several processes. It feels like an incredibly heavyweight UI component, just judging from the lag between when the icon is clicked and when the list of networks pops up.
