Re: acceptsMouseMovedEvents?

From the Cocoa documentation:

"...because mouse-moved events occur so often and can bog down the
event queue, an NSView must explicitly request its NSWindow to watch
for them using NSWindow’s setAcceptsMouseMovedEvents: method. Tracking
rectangles, described below, are a less expensive way of following the
mouse’s location."

Events & Other Input > Basic Event Handling

and specifically the article entitled "Handling Mouse Events in Views".
