    I have a 2.4UMBP with 4Gb DDR3 ram and a 7200rpm hdd.

    Im on 10.6.2, After i open iMovie 09 and while using it my system becomes very laggy (also some beachballs here and there), why is that? I have nothing else opened.

    This never happened a few months ago and i don't believe any app is causing this.

    Thank you for anyone who helps.

    Are you editing large video files? I've recently been editing HD content in iMovie and am constantly getting slow down and beach balls myself. Also I think iMovie 09 is quite a buggy app when used I
