For what it's worth, I have always been unclear on what the Win32::GUI doco means by "the event is not passed to the default event processor". Any clarification, anywhere, would be useful.

Glenn, I wouldn't expect it to prevent it from being checked. Do you expect this behaviour from the Windows control itself or from Win32::GUI? Certain actions for some controls have a "pre-change" notification (e.g. the TCN_SELCHANGING notification sent when a tab is *about* to change), which can be used to prevent the change, but I don't see anything like that on MSDN for a checkbox. Or do you expect this from Win32::GUI? I know a return value of 0 prevents the "default action" from taking place, but I see that as a "post-change" action, if that makes sense. (I'm not sure where that action is defined). Or am I missing your point entirely?
