Re: Accuracy of timers?

As others have noted, NSTimers are bound by the runloops they operate in. Though you can always spawn a dedicated thread, create a run loop, add your timer, and then go; since nothing else is in the runloop, the latency should be quite low. I'd try that first, and see if it meets your nee

non-movable fullscreen window

    Initially I created a window with a title-bar (so, I created a window with border and resizable/movable properties).

RE: performSelectorOnMainThread primitives for withObject
