Message with dwData = 0 (generate by SHAppBarMessage) are not required, but should be handled to allow proper positioning of the interfaces for the new vista icons. The minimum needed for correct positioning is to handle ABM_GETTASKBARPOS and to have the returned rectangle and edge correspond to the location of the interface containing the tray.
What's significant here is that ABM_GETTASKBARPOS isn't documented to set uEdge, but that Explorer does indeed set it. And the volume control slider depends on that. Our code didn't set it, which wasn't trivial to debug. (It still doesn't, but I'm onto it.)
