Isolating WM_LBUTTONUP & WM_LBUTTONDBLCLK

[Klass]

I would like to isolate WM_LBUTTONUP & WM_LBUTTONDBLCLK from each other when capturing a mouse event on an icon in the system tray. If you notice with the LBUTTONUP I have added a Shift key to the click in order to separate but I'm not too sure if there is a way around this. Like a timed delay on the double click or something. But when I double click I get the button up command as well. Any thoughts?
