c# - Finding missing mouse clicks -


i working c# winforms application i'm not familiar with. control intended draggable, , indeed draggable if user starts drag in parts of control, not in others.

the control contains several child controls, , it's belief of these child controls capturing mouse clicks before parent control sees them, hence failure in areas. have confirmed in debugger mouse-down handler parent invoked when user clicks on particular child controls.

given know clicks being captured/suppressed before handler, there way in debugger (or otherwise) determine clicks going? staring @ code has not been successful because don't know start.

bundled visual studio comes niftly little program called spy++. allows log messages being sent windows, , shows 'real' structure of win32 controls within window (many controls not controls custom painted screen areas). should able, inspection, find culprit message log.
