I understood that from your original post.

What I'm saying is that WM_LBUTTONUP is the wrong thing - you didn't
actually have to add anything there (and, you missed a break statement).

This app is using TRAY_NOTIFYICON for the message. Set a break on that case
(it's already in the code). From that message, you can examine the
wParam/lParam to determine what caused the event (for example, left button
up. Then take the appropriate action.
