javascript - $(window).mouseup handler in a Chrome extension is breaking Flash -

i'm working on google chrome extension monitors mouse events. reason following javascript code in extension's content script causing embedded flash content break:

$(window).mouseup(function() {     // benign stuff }); 

if mousedown inside flash element, never registers mouseup , appears though you're still holding mouse button down though you've let go. @ first thought kind of event bubbling issue, method swallowing event, tried returning true (and false matter) didn't seem have effect. ideas?

well, no response peanut gallery after few days, figured out on lonesome:

// bad $(window).mouseup(function() { ... });  // window.addeventlistener("mouseup", function(event) { ... });
