Christof or Ed,

Could one of you inform the poorly educated among us (that's me at least) of what a "callback is?? I would appreciate it.

regards,

>You needs one? *g* If what you get looks like a message, VFP processes it and fires the event for the forms. For example, with Shell_NotifyIcon you can use the WM_MOUSEMOVE command (see KB article Q176085). Windows sends a WM_MOUSEMOVE messages passing the Icon message as the position. VFP processes the message and fires the MouseMove event passing the icon message as the mouse coordinates, IF (and only if *g*) the window is visible and at least 520 pixel wide and 1 pixel high (because the systray messages start with 0x200).
