4. Some questions on notification icons (tested on Windows 7):
- When pressing Enter on a focused notification icon, why are two NIN_KEYSELECT notifications sent to the associated application? (i.e. when using Windows 2000 or newer behaviour), Space was OK, as I remember.
- In the main notification icon area, why are WM_XBUTTONDOWN/WM_XBUTTONUP notifications sent when the 'X' buttons are pressed over another icon?
