I have a tray app that has a window and I do not want it to be alt-tabbable.
It doesn't show up in the alt-tab window right now unless the user is using a full screen program
1. why does it show up doing a full screen program?
2. What is the best thing to override to not allow alt-tab to work properly (just capture WM_MAXIMIZE in WndProc?) and leave the window minimized.
